aditya，

Hi aditya,

OpenFileDialog dialog = new OpenFileDialog();
           dialog.Filter =
              "txt files (*.txt)|*.txt|All files (*.*)|*.*";
           dialog.InitialDirectory = "C:\\";
           dialog.Title = "Select a text file";
           if (dialog.ShowDialog() == DialogResult.OK)
           {
               string fname = dialog.FileName;
                         richTextBox1.Text= System.IO.File.ReadAllText (fname);

           }

尝试使用此代码

try this code

您可以使用过滤器仅显示DOC和TXT文件

You can take use of Filters to show only DOC and TXT files

OpenFileDialog dialog1 = new OpenFileDialog();
dialog1.Filter = "txt files (*.txt)|*.txt| DOC files (*.doc)|*.doc";

您可以使用 LoadFile 方法在Richtextbox中加载文件

you can load files in Richtextbox, by using LoadFile method

//for DOC File
richTextBox1.LoadFile(FilePath, RichTextBoxStreamType.RichText); 

//for TXT File, just change streamtype to plain text
richTextBox1.LoadFile(FilePath,  RichTextBoxStreamType.PlainText); 

尝试一下

对话框已打开对话框ID

try this

dialog was openDialog ID

dialog.Filter = "txt files |*.txt|Word Documents|*.doc";
