如何在表单标题中显示当前打开文件的名称？

Question

我正在制作一个文本编辑器，我想在表单标题中显示当前打开文件的名称（就像记事本一样，它显示“无标题 - 记事本”或““文件 - 记事本”）。

我假设这是使用 SaveFileDialog 和 OpenFileDialog 完成的，所以我将发布我当前的代码。

打开文件：

  private void OpenFile()
        {
            NewFile();
            OpenFileDialog ofd = new OpenFileDialog();
            ofd.Title = "Open File";
            ofd.FileName = "";
            ofd.Filter = "Rich Text Files (*.rtf)|*.rtf|Text Document (*.txt)|*.txt|Microsoft Word Document (*.doc)|*.doc|Hypertext Markup Language Document (*.html)|*.html";
            if (ofd.ShowDialog() != DialogResult.OK) return;
            StreamReader sr = null;
            try
            {
                sr = new StreamReader(ofd.FileName);
                this.Text = string.Format("{0} - Basic Word Processor", ofd.FileName);
                richTextBoxPrintCtrl1.Text = ofd.FileName;
                richTextBoxPrintCtrl1.Text = sr.ReadToEnd();
                filepath = ofd.FileName;
                richTextBoxPrintCtrl1.LoadFile(fileName, RichTextBoxStreamType.RichText);

            }
            catch 
            { 
            }
            finally
            {
                if (sr != null) sr.Close();
            }

保存文件

private void SaveFileAs()
        {
            SaveFileDialog sfdSaveFile = new SaveFileDialog();
            sfdSaveFile.Title = "Save File";
            sfdSaveFile.FileName = "Untitled";
            sfdSaveFile.Filter = "Rich Text Files (*.rtf)|*.rtf|Text Document (*.txt)|*.txt|Microsoft Word Document (*.doc)|*.doc|Hypertext Markup Language Document (*.html)|*.html";
            if (sfdSaveFile.ShowDialog() == DialogResult.OK)
                try
                {
                    filepath = sfdSaveFile.FileName;
                    SaveFile();
                    this.Text = string.Format("{0} - Basic Word Processor", sfdSaveFile.FileName);
                }
                catch (Exception exc)
                {

                }


void SetWindowTitle(string fileName) {
    this.Text = string.Format("{0} - Basic Text Editor", System.IO.Path.GetFileNameWithoutExtension(OpenFileDialog.Filename));

如何获取文件名并将其放在表单的标题中（就像记事本一样，文件名后跟文本编辑器的名称）。

打开时。 . .

private void OpenFile()
{
        OpenFileDialog ofd = new OpenFileDialog();
        ofd.Title = "Open File";
        ofd.FileName = "";
        ofd.Filter = "Rich Text Files (*.rtf)|*.rtf|Text Document (*.txt)|*.txt|Microsoft Word Document (*.doc)|*.doc|Hypertext Markup Language Document (*.html)|*.html";
        ofd.ShowDialog();
        try
        {
            // just one line is added
            this.Text = string.Format("{0} - MyNotepad", Path.GetFileName(ofd.Filename));
            richTextBoxPrintCtrl1.Text = ofd.FileName;
            StreamReader stread = new StreamReader(richTextBoxPrintCtrl1.Text);
            richTextBoxPrintCtrl1.Text = stread.ReadToEnd();
            stread.Close();
            richTextBoxPrintCtrl1.LoadFile(fileName, RichTextBoxStreamType.RichText);
        }
        catch { } 
    }

在保存时。 . .

private void SaveFileAs()
{
    SaveFileDialog sfdSaveFile = new SaveFileDialog();
    sfdSaveFile.Title = "Save File";
    sfdSaveFile.FileName = "Untitled";
    sfdSaveFile.Filter = "Rich Text Files (*.rtf)|*.rtf|Text Document (*.txt)|*.txt|Microsoft Word Document (*.doc)|*.doc|Hypertext Markup Language Document (*.html)|*.html";
    if (sfdSaveFile.ShowDialog() == DialogResult.OK)
        try
        {
            richTextBoxPrintCtrl1.SaveFile(sfdSaveFile.FileName, RichTextBoxStreamType.RichText);
            filepath = sfdSaveFile.FileName;
            // just one line is added
            this.Text = string.Format("{0} - MyNotepad", Path.GetFileName(sfd.Filename));
        }
        catch (Exception exc)
        {

        }
}

只是更新

托比-The empty catch blocks are needed. If the user cancels the ofd or sfd without the catch block, the program crashes. It keeps the program from crashing

您不需要 catch 块来检查用户是否选择了确定/取消。

OpenFileDialog 和 SaveFileDialog 具有返回 DialogResult 的方法 ShowDialog

DialogResult.OK 的值告诉用户已经选择了要打开/保存的文件并且没有取消操作。

OpenFile 示例

私有 void OpenFile() { OpenFileDialog ofd = new OpenFileDialog(); ofd.Title = "打开文件"; ofd.FileName = ""; ofd.Filter = "富文本文件 (.rtf)|.rtf|文本文档 (.txt)|.txt|Microsoft Word 文档 (.doc) |.doc|超文本标记语言文档 (.html)|.html";

    if (ofd.ShowDialog() == DialogResult.OK)
    {     
        // just one line is added
        this.Text = string.Format("{0} - MyNotepad", Path.GetFileName(ofd.Filename));
        richTextBoxPrintCtrl1.Text = ofd.FileName;
        StreamReader stread = new StreamReader(richTextBoxPrintCtrl1.Text);
        richTextBoxPrintCtrl1.Text = stread.ReadToEnd();
        stread.Close();
        richTextBoxPrintCtrl1.LoadFile(fileName, RichTextBoxStreamType.RichText);
    }
}

你可以把它包装成这样的函数：

void SetWindowTitle(string fileName) {
    this.Text = string.Format("{0} - MyEditor", System.IO.Path.GetFileName(fileName));
}

..并传入对话框文件名..

编辑：

你的问题是你没有调用我给你的函数。你有我上面给你的功能..但你没有调用它。

替换这个：

this.Text = string.Format("{0} - Basic Word Processor", sfdSaveFile.FileName);

有了这个：

SetWindowTitle(sfdSaveFile.FileName);

然后替换这个：

this.Text = string.Format("{0} - Basic Word Processor", ofd.FileName);

有了这个：

SetWindowTitle(ofd.FileName);
