RichTextBox中插入图片的方法

1.      通过剪切板来实现。

public void InsertImage() {

 string lstrFile = fileDialog.FileName;

 Bitmap myBitmap = new Bitmap(lstrFile);

 // Copy the bitmap to the clipboard.

 Clipboard.SetDataObject(myBitmap);

 // Get the format for the object type.

 DataFormats.Format myFormat = DataFormats.GetFormat (DataFormats.Bitmap);

 // After verifying that the data can be pasted, paste

 if(myRichTextBox.CanPaste(myFormat)) {

    myRichTextBox.Paste(myFormat);

 }

 else {

    MessageBox.Show("The data format that you attempted site" +

      " is not supportedby this control.");

 }

}
