如何在SaveFileDialog中使用复选框选项作为只读？ [英] How to Use a checkbox option as readonly in SaveFileDialog ?

问题描述

我想创建一个 SaveFileDialog 框，其中包含 CheckBox 选项，只读或不是



我有一个事件按钮的代码

I would like to make a SaveFileDialog box with a CheckBox option for read only or not

I have this code for a event button

private void button1_Click(object sender, EventArgs e)
   {
     Stream myStream;
     SaveFileDialog saveFileDialog1 = new SaveFileDialog();

     saveFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";
     saveFileDialog1.FilterIndex = 2;
     saveFileDialog1.RestoreDirectory = true;


     if (saveFileDialog1.ShowDialog() == DialogResult.OK)
     {
       if ((myStream = saveFileDialog1.OpenFile()) != null)
       {
         // Code to write the stream goes here.
         myStream.Close();
       }
     }
   }

推荐答案

您可以使用只读选项 OpenFileDialog ，而非 SaveFileDialog 。

You can use read only option in OpenFileDialog, not SaveFileDialog.

SaveFileDialog 没有 ReadOnly 并且它使没意思，因为你想保存一个文件，你不能写入只读文件。



你需要使用 OpenFileDialog ，其中包含 ShowReadOnly 属性，您可以将其设置为 True 。

SaveFileDialog has no ReadOnly and it makes no sense as you want to save a file, and you can't write to a read-only file.

You need to use the OpenFileDialog which has a ShowReadOnly property which you can set to True.

那么这可能是什么解决方案呢？制作我自己的SaveFileDialog
