SaveFileDialog - （文件路径）不存在。验证是否给出了正确的文件名

Question

我想保存一个新的文件名，但现在我只能保存重写文件。每次我尝试保存新文件名时，都会出现一个消息框，其中包含警告对话框：

（文件路径）不存在。验证正确的文件名 给。”

下面是我的代码，任何人都可以请指出缺少什么？谢谢。

private void button5_Click(object sender, EventArgs e) 
{ 
    SaveFileDialog saveFileDialog1 = new SaveFileDialog(); 
    saveFileDialog1.Title = "Save File"; 
    saveFileDialog1.CheckFileExists = true; 
    saveFileDialog1.CheckPathExists = true; 
    saveFileDialog1.Filter = "Text files (*.txt)|*.txt| CONF(*.conf)|*.conf|All files (*.*)|*.*"; 
    saveFileDialog1.FilterIndex = 2; 
    saveFileDialog1.ShowDialog(); 

    if (saveFileDialog1.FileName != "") 
    { 
     // Saves the Image via a FileStream created by the OpenFile method. 
     System.IO.FileStream fs = (System.IO.FileStream)saveFileDialog1.OpenFile(); 
     // Saves the Image in the appropriate ImageFormat based upon the 
     // File type selected in the dialog box. 
     // NOTE that the FilterIndex property is one-based. 
     switch (saveFileDialog1.FilterIndex) 
     { 
      case 1: 
       saveFileDialog1.FileName = saveFileDialog1.FileName + ".txt"; 
       break; 
      case 2: 
       saveFileDialog1.FileName = saveFileDialog1.FileName + ".conf"; 
       break; 
      default: 
       saveFileDialog1.FileName = saveFileDialog1.FileName + ".txt"; 
       break; 
     } 

     fs.Close(); 
    } 
}

您需要设置CheckFileExists和CheckPathExists为假以防止对话框检查文件的存在，否则如果用户指定路径，对话框会显示警告：

saveFileDialog1.CheckFileExists = false; 
saveFileDialog1.CheckPathExists = false;
