如何将图片转换为RTF编码格式？

楼主你可以参考下面的代码：

public void InsertImage()
        {
            OpenFileDialog fileDialog = new OpenFileDialog();
            fileDialog.ShowDialog();
            string lstrFile = fileDialog.FileName;
            Bitmap myBitmap = new Bitmap(lstrFile);
            // 拷贝位图到剪贴板  
            Clipboard.SetDataObject(myBitmap);
            // 获取对象格式  
            DataFormats.Format myFormat = DataFormats.GetFormat(DataFormats.Bitmap);
            // 验证并粘贴位图  
            if (this.richTextBox1.CanPaste(myFormat)) { this.richTextBox1.Paste(myFormat);}
            else
            {
                MessageBox.Show("The data format that you attempted site" +" is not supportedby this control.");

            }
        }

BASE64格式
System.IO.MemoryStream m = new System.IO.MemoryStream();
System.Drawing.Bitmap bp = new System.Drawing.Bitmap(@“c:\a.GIF”);
bp.Save(m, System.Drawing.Imaging.ImageFormat.Gif);
byte[]b= m.GetBuffer();
string base64string=Convert.ToBase64String(b);

MemoryStream ms = new MemoryStream();
pictureBox1.Image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);

byte[] buffer = new byte[ms.Length];
ms.Position = 0;
ms.Read(buffer, 0, buffer.Length);
ms.Close();
File.WriteAllBytes("", buffer);
File.WriteAllText("a.txt", Convert.ToBase64String(buffer));
