如何把XML文档显示在text文本框中？
如题。
找了找，好像应该用XmlTextWriter，但是XmlTextWriter只能输出到Console.out或者文件中。

------解决方案--------------------
带格式的显示到文本框中可以用如下的方法：
XmlDocument doc = new XmlDocument();
doc.Load( "xmlfile.xml ");
StringWriter writer1 = new StringWriter();
XmlTextWriter writer2 = new XmlTextWriter(writer1);
writer2.Formatting = Formatting.Indented;
writer2.Indentation=1;
writer2.IndentChar= '\t ';
doc.WriteTo(writer2);
this.textBox1.Text = writer1.ToString();
