RTF 内容合并 (刚做完技术支持,查了一下资料记录一下)

给个同事做了一下支持：关于RichTextBox中的内容合并，尝试了好几总办法：什么去文件头、文件尾等等均未成功。后来找到一段代码改造了一下，解决问题，如下：

 1public void RTFMerge()
 2{
 3            richTextBox1.SelectionStart = 0;
 4            richTextBox1.SelectionLength = richTextBox1.Text.Length;
 5
 6            richTextBox2.SelectionStart = 0;
 7            richTextBox2.SelectionLength = richTextBox2.Text.Length;
 8
 9
10            richTextBox3.SelectionStart = 0;
11            richTextBox3.SelectionLength = richTextBox3.Text.Length;
12
13            richTextBox3.SelectedRtf = richTextBox1.SelectedRtf;
14            richTextBox3.SelectionStart = richTextBox3.Text.Length;
15            richTextBox3.SelectionLength = 0;
16            richTextBox3.SelectedText = "\n";
17            richTextBox3.SelectionStart = richTextBox3.Text.Length;
18            richTextBox3.SelectionLength = 0;
19            richTextBox3.SelectedRtf = richTextBox2.SelectedRtf;
20
21
22            richTextBox1.SelectionStart = 0;
23            richTextBox1.SelectionLength = 0;
24            richTextBox2.SelectionStart = 0;
25            richTextBox2.SelectionLength = 0;
26}
