拷贝文件效果：
拷贝文件代码：
1 private void button1_Click(object sender, EventArgs e) 2 { 3 try 4 { 5 string path1 = textBox1.Text.Trim(); 6 string path2 = textBox2.Text.Trim(); 7 if (File.Exists(path1) == true) 8 { 9 File.Copy(path1, path2); 10 MessageBox.Show("拷贝成功"); 11 } 12 } 13 catch 14 { 15 MessageBox.Show("拷贝失败"); 16 } 17 }
移动文件：
代码：
1 private void button2_Click(object sender, EventArgs e) 2 { 3 try 4 { 5 string path1 = textBox1.Text.Trim(); 6 string path2 = textBox2.Text.Trim(); 7 if (File.Exists(path1) == true) 8 { 9 File.Move(path1, path2); 10 MessageBox.Show("移动成功"); 11 } 12 } 13 catch 14 { 15 MessageBox.Show("移动失败"); 16 } 17 }
删除文件
代码:
1 private void button3_Click(object sender, EventArgs e) 2 { 3 try 4 { 5 string path = textBox1.Text.Trim(); 6 if (File.Exists(path) == true) 7 { 8 File.Delete(path); 9 MessageBox.Show("删除成功"); 10 } 11 } 12 catch 13 { 14 MessageBox.Show("删除失败"); 15 } 16 }
