RichTextbox 粘贴方法究竟是如何工作的？我想将图像插入 RTB。如果我使用 Clipboard.SetImage(image); 然后是 RTB.Paste(); 它工作正常。但我想自己做。我有以下代码。但它不起作用：
byte[] byteArray = null;
using (MemoryStream ms = new MemoryStream())
{
image.Save(ms, ImageFormat.Png);
ms.Seek(0, 0);
byteArray = ms.ToArray();
}
string hexString = "";
foreach (byte b in byteArray)
{
hexString += b.ToString("x2");
}
string mpic = @"{\pict\pngblip\picw396\pich396\picwgoal225\pichgoal225 ";
mpic += hexString;
mpic += "}";
Console.WriteLine(mpic);
return mpic;
我发现使用 Paste() 方法后，hexString 中的值与richTextbox 中的值不同。
如果我使用正确的十六进制值，这可以正常工作。
string mpic = @"{\pict\wmetafile8\picw396\pich396\picwgoal225\pichgoal225 ";
mpic += hexString;
mpic += "}";
我想我需要的只是将图像转换为 WMF hexa 值。但我不知道该怎么做。
如果它有帮助，这就是有效的：
