如果文件存在，则自动选中复选框 [英] Automatically check a checkbox if file exists

问题描述

I want to create a program such that if the file exists, the checkbox will auto check.

我尝试过：

What I have tried:

private void autoCheckChkBoxes(CheckBox theChkBox, TextBox theTxtBox)
    {
       private void button3_Click(object sender, EventArgs e)
{
  //check whether the file is exist or not
  if (string curFile = @"C:\s\test.txt")
  {

  }
  else
  {

  }
}

推荐答案

private void button3_Click(object sender, EventArgs e)
{
    autoCheckChkBoxes(checkBoxObj,TextBox);
}
private void autoCheckChkBoxes(CheckBox theChkBox, TextBox theTxtBox)
{
   string curFile = @"C:\s\test.txt"
   theChkBox.checked=system.IO.File.Exist(curFile);
}

希望它对您有用。

Hope it works for you.
