protected void btnUpload_Click(object sender, EventArgs e)

{

【方法一】

if (FileUpload1.PostedFile.FileName == "")
{
Label4.Text = "请选择文件！";
}
else
{
string filepath = FileUpload1.PostedFile.FileName;
string filename = filepath.Substring(filepath.LastIndexOf("//") + 1);
string serverpath = Server.MapPath("image/") + filename;
FileUpload1.PostedFile.SaveAs(serverpath);
Label4.Text = "上传成功！";
}

//***********************************

【方法二】

//if (FileUpload1.HasFile)
//{
// try
// {
// int startIndex = this.FileUpload1.FileName.LastIndexOf(@"\") + 1;
// string fileName = this.FileUpload1.FileName.Substring(startIndex);//文件名的获取
// string phyFileName = this.Server.MapPath("Image") + @"\" + fileName + ".bmp";
// this.FileUpload1.SaveAs(phyFileName);
// Label4.Text = "客户端路径：" + FileUpload1.PostedFile.FileName + " " +
// "文件名：" + System.IO.Path.GetFileName(FileUpload1.FileName) + " " +
// "文件扩展名：" + System.IO.Path.GetExtension(FileUpload1.FileName) + " " +
// "文件大小：" + FileUpload1.PostedFile.ContentLength + " KB " +
// "文件MIME类型：" + FileUpload1.PostedFile.ContentType + " " +
// "保存路径：" + Server.MapPath("upload") + "\\" + FileUpload1.FileName;
// }
// catch (System.Exception ex)
// {
// Label4.Text = "发生错误：" + ex.Message.ToString();
// }

//}
//else
//{
// Label4.Text = "没有选择要上传的文件！";
// //message.AjaxResponeSrcipt(UpdatePanel1,this.GetType(),"提交成功");
//}
//}

【方法三】
//bool fileOK = false;
//string path = Server.MapPath("Image");
//if (FileUpload1.HasFile)
//{
// String fileExtension = System.IO.Path.GetExtension(FileUpload1.FileName).ToLower();
// String[] allowedExtensions = { ".gif", ".png", ".bmp", ".jpg" };
// for (int i = 0; i < allowedExtensions.Length; i++)
// {
// if (fileExtension == allowedExtensions[i])
// {
// fileOK = true;
// }
// }
//}
//if (fileOK)
//{
// try
// {
// FileUpload1.SaveAs(path + FileUpload1.FileName);
// Label4.Text = "文件上传成功.";
// Label4.Text = "原文件路径：" + FileUpload1.PostedFile.FileName + " " +
// "文件大小：" + FileUpload1.PostedFile.ContentLength + "字节 " +
// "文件类型：" + FileUpload1.PostedFile.ContentType + " ";
// }
// catch (Exception ex)
// {
// Label4.Text = "文件上传不成功.";
// }
//}
//else
//{
// Label4.Text = "只能够上传图片文件.";
//}

}
