在excel开发中一些常用的方法。

获取选择的单元格

Excel.Range r = (Excel.Range)Application.ActiveCell;

获取指定单元格
wks是当前活动的Worksheet
Excel.Range cell1 = (Excel.Range)wks.Cells[next_row, 1];

删除一行
Excel.Range sel_row_range = (Excel.Range)wks.Rows["2:2", Type.Missing];
//删除第二行
sel_row_range.Delete(Excel.XlDeleteShiftDirection.xlShiftUp);

设置range颜色
Excel.Range range = this.Cells[1, 1];
range.Interior.Color = 0x00ff00;

0x0000ff 红色
0x00ff00 绿色
0xff0000 蓝色

设置单元格计算函数
//显示计算结果的单元格
Excel.Range math_range = get_Range("A5","A5");
//设置单元格表达式
math_range.FormulaR1C1 = "=CalculateArea(R[-2]C[-1]:R[-2]C)";
R[-2]C[-1]:R[-2]C
意思是，从当前单元格开始算行数为当前行-2，列数为当前列-1，到达单元格为当前行-2，和当前列相等

设置单元格类型
//设置单元格类型为文本
cell2.NumberFormatLocal = "@";

设置公式
例 E3=B3*D3
Excel.Range r = (Excel.Range)wks.cells[3,5];
r.FormulaR1C1 = "=RC[-3]*RC[-1]";

设置区域字体
private void SetRangeFont(Excel.Range range, string font_name, int font_size)
{
Excel.Font target_font = range.Font;
target_font.Name = font_name;
target_font.Size = font_size;
target_font.Strikethrough = false;
target_font.Superscript = false;
target_font.Subscript = false;
target_font.OutlineFont = false;
target_font.Shadow = false;
target_font.Underline = Excel.XlUnderlineStyle.xlUnderlineStyleNone;
target_font.ThemeColor = Excel.XlThemeColor.xlThemeColorLight1;
target_font.TintAndShade = 0;
target_font.ThemeFont = Excel.XlThemeFont.xlThemeFontNone;
}

设置选择单元格
Excel.Range range = this.Cells[1, 1];
range.Select();

设置选择行
Excel.Range range = (Excel.Range)this.Rows[1, missing];
range.Select();

通过代号获取range
Excel.Range range = get_Range("A1", "B3");

设置Range的详细属性，包括颜色，是否边框为黑色实线等

private void SetRangeColor(Excel.Range range,Excel.XlThemeColor color)
{
range.Interior.Pattern = Excel.XlPattern.xlPatternSolid;
range.Interior.PatternColorIndex = Excel.XlPattern.xlPatternAutomatic;
range.Interior.ThemeColor = color;
range.Interior.TintAndShade = 0.89999;
range.Interior.PatternTintAndShade = 0;
range.Borders[Excel.XlBordersIndex.xlDiagonalDown].LineStyle = Excel.XlLineStyle.xlLineStyleNone;
range.Borders[Excel.XlBordersIndex.xlDiagonalUp].LineStyle = Excel.XlLineStyle.xlLineStyleNone;
range.Borders[Excel.XlBordersIndex.xlEdgeLeft].LineStyle = Excel.XlLineStyle.xlLineStyleNone;
range.Borders[Excel.XlBordersIndex.xlEdgeTop].LineStyle = Excel.XlLineStyle.xlLineStyleNone;
range.Borders[Excel.XlBordersIndex.xlEdgeBottom].LineStyle = Excel.XlLineStyle.xlContinuous;
range.Borders[Excel.XlBordersIndex.xlEdgeBottom].ColorIndex = 0;
range.Borders[Excel.XlBordersIndex.xlEdgeBottom].TintAndShade = 0;
range.Borders[Excel.XlBordersIndex.xlEdgeBottom].Weight = Excel.XlBorderWeight.xlThin;
range.Borders[Excel.XlBordersIndex.xlEdgeRight].LineStyle = Excel.XlLineStyle.xlLineStyleNone;
range.Borders[Excel.XlBordersIndex.xlInsideVertical].LineStyle = Excel.XlLineStyle.xlLineStyleNone;
range.Borders[Excel.XlBordersIndex.xlInsideHorizontal].LineStyle = Excel.XlLineStyle.xlLineStyleNone;
range.Borders[Excel.XlBordersIndex.xlDiagonalDown].LineStyle = Excel.XlLineStyle.xlLineStyleNone;
range.Borders[Excel.XlBordersIndex.xlDiagonalUp].LineStyle = Excel.XlLineStyle.xlLineStyleNone;

range.Borders[Excel.XlBordersIndex.xlEdgeLeft].LineStyle = Excel.XlLineStyle.xlContinuous;
range.Borders[Excel.XlBordersIndex.xlEdgeLeft].ColorIndex = 0;
range.Borders[Excel.XlBordersIndex.xlEdgeLeft].TintAndShade = 0;
range.Borders[Excel.XlBordersIndex.xlEdgeLeft].Weight = Excel.XlBorderWeight.xlThin;
range.Borders[Excel.XlBordersIndex.xlEdgeTop].LineStyle = Excel.XlLineStyle.xlContinuous;
range.Borders[Excel.XlBordersIndex.xlEdgeTop].ColorIndex = 0;
range.Borders[Excel.XlBordersIndex.xlEdgeTop].TintAndShade = 0;
range.Borders[Excel.XlBordersIndex.xlEdgeTop].Weight = Excel.XlBorderWeight.xlThin;
range.Borders[Excel.XlBordersIndex.xlEdgeBottom].LineStyle = Excel.XlLineStyle.xlContinuous;
range.Borders[Excel.XlBordersIndex.xlEdgeBottom].ColorIndex = 0;
range.Borders[Excel.XlBordersIndex.xlEdgeBottom].TintAndShade = 0;
range.Borders[Excel.XlBordersIndex.xlEdgeBottom].Weight = Excel.XlBorderWeight.xlThin;
range.Borders[Excel.XlBordersIndex.xlEdgeRight].LineStyle = Excel.XlLineStyle.xlContinuous;
range.Borders[Excel.XlBordersIndex.xlEdgeRight].ColorIndex = 0;
range.Borders[Excel.XlBordersIndex.xlEdgeRight].TintAndShade = 0;
range.Borders[Excel.XlBordersIndex.xlEdgeRight].Weight = Excel.XlBorderWeight.xlThin;
range.Borders[Excel.XlBordersIndex.xlInsideVertical].LineStyle = Excel.XlLineStyle.xlContinuous;
range.Borders[Excel.XlBordersIndex.xlInsideVertical].ColorIndex = 0;
range.Borders[Excel.XlBordersIndex.xlInsideVertical].TintAndShade = 0;
range.Borders[Excel.XlBordersIndex.xlInsideVertical].Weight = Excel.XlBorderWeight.xlThin;
range.Borders[Excel.XlBordersIndex.xlInsideHorizontal].LineStyle = Excel.XlLineStyle.xlContinuous;
range.Borders[Excel.XlBordersIndex.xlInsideHorizontal].ColorIndex = 0;
range.Borders[Excel.XlBordersIndex.xlInsideHorizontal].TintAndShade = 0;
range.Borders[Excel.XlBordersIndex.xlInsideHorizontal].Weight = Excel.XlBorderWeight.xlThin;
}

隐藏
Excel.Range child_range = (Excel.Range)wks.Rows["3:3", Type.Missing];
child_range.EntireRow.Hidden = true;

另存并加载到当前
wk.SaveAs(file_path, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Excel.XlSaveAsAccessMode.xlNoChange, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

另存不加载到当前
wk.SaveCopyAs(file_path);

合并单元格
private void MergeCells(string col_name, int start_row, int end_row)
{
Excel.Worksheet wks = m_excell_app.ActiveSheet as Excel.Worksheet;
string str1 = col_name + start_row.ToString();
string str2 = col_name + end_row.ToString();
Excel.Range r1 = (Excel.Range)wks.get_Range(str1, str2);
r1.Merge(Type.Missing);
}

设置居中，靠左
range.HorizontalAlignment = Excel.XlHAlign.xlHAlignLeft;
range.HorizontalAlignment = Excel.XlHAlign.xlHAlignCenter;

设置上锁区域
Excel.Worksheet wks = m_excell_app.ActiveSheet as Excel.Worksheet;
foreach (Excel.AllowEditRange aer in wks.Protection.AllowEditRanges)
{
aer.Delete();
}
wks.Protection.AllowEditRanges.Add("s", (Excel.Range)wks.Columns["C:H", Type.Missing], Type.Missing);
wks.Protection.AllowEditRanges.Add("s1", (Excel.Range)wks.Columns["X:AR", Type.Missing], Type.Missing);
int i = 2;
foreach (Excel.Range e in wks.UsedRange.Rows)
{
Excel.Range cell = (Excel.Range)wks.Cells[e.Row, 17];
if (cell.Value2 == null)
{
wks.Protection.AllowEditRanges.Add("s" + i.ToString(), cell, Type.Missing);
i++;
}
else
{
try
{
Convert.ToDouble(cell.FormulaR1C1.ToString());
wks.Protection.AllowEditRanges.Add("s" + i.ToString(), cell, Type.Missing);
i++;
}
catch (Exception ex)
{

}
}
}
wks.Protect(Type.Missing, true, true, false, false, false, false, false, false, false, false, false, false, false, false, false);
