C# 复制与删除文件的实现方法

1、首先是复制文件

首先打开我们的对话框获得文件路径,当然也可以直接编写路径


private void BtnAddFile_Click(object sender, RoutedEventArgs e) 
  { 
   OpenFileDialog openFileDialog = new OpenFileDialog(); 
   if (openFileDialog.ShowDialog() == System.Windows.Forms.DialogResult.OK) 
   { 
    string path = openFileDialog.FileName; 
    // System.Windows.Forms.MessageBox.Show(path); 
    MyFile.addFile(path); 
   } 
  }
Copy after login

然后是复制文件的方法买这里我写的是添加,是根据我的项目来的

MyFile是一个文件操作类,OpenFileDialog需要添加引用


public static void addFile(string path)  
    { 
      string[] s = path.Split('\\'); 
 
      try 
      { 
        File.Copy(path, "E:\\Share\\"+s[s.Length-1], true);  

     //path是你要复制的文件,第二个是目标路径,注意要获得文件名      
  } 
  catch (Exception ex)  
  { 
    System.Windows.Forms.MessageBox.Show(ex.Message); 
  } 
}
Copy after login

string[] s = path.Split("\\");这是一个分割字符串的方式,我们需要获得文件名,然后拼接成目标路径,我们是不能直接复制文件到文件夹中的

2、删除


public static void deleteFile(string path) 
  { 
   if (System.IO.File.Exists(path)) 
   { 
    try 
    { 
     System.IO.File.Delete(path); 
    } 
    catch (System.IO.IOException e) 
    { 
     Console.WriteLine(e.Message); 
     return; 
    } 
   } 
  }
Copy after login
