这是什么错误 得怎么改啊

顺便问下[DllImport("user32")] 这么写对吗
USER32需要自己下吗

[解决办法]
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;

namespace WindowsApplication13
{

public partial class Form1 : Form
{
[DllImport("user32")]
public static extern void mouse_event(int dwFlags, int dx, int dy, int dwData, int dwExtraInfo);

private readonly int MOUSEEVENTF_LEFTDOWN = 0x2;
private readonly int MOUSEEVENTF_LEFTUP = 0x4;

public Form1()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{

}


private void button1_Click(object sender, EventArgs e)
{
mouse_event(MOUSEEVENTF_LEFTDOWN, 10 * 65536 / 1024, 10 * 65536 / 768, 0, 0);
mouse_event(MOUSEEVENTF_LEFTUP, 10 * 65536 / 1024, 10 * 65536 / 768, 0, 0);


}
