C# 读写内存---by wgscd

测试 在Windows窗口 放个Timer用于读取扫雷游戏的计时。

按钮点击讲设置 计时为0；

先可看怎么找内存地址： http://jingyan.baidu.com/article/93f9803fe721f1e0e56f5572.html

public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
timer1.Interval= 500;
}
private int baseAddress = 0x006A9EC0; //游戏内存基址
private string processName = "PlantsVsZombies"; //游戏进程名字
//读取制定内存中的值
public int ReadMemoryValue(int baseAdd)
{
return Helper.ReadMemoryValue(baseAdd, processName);
}

    //将值写入指定内存中
    public void WriteMemory(int baseAdd, int value)
    {
        Helper.WriteMemoryValue(baseAdd, processName, value);
    }


    private void button1_Click(object sender, EventArgs e)
    {
        try
        {
            baseAddress = 0x0100579C;
            // int.Parse(txtBaseAddress.Text.Trim());

            processName = txtProcessName.Text.Trim();

            processName = "winmine";//干脆设置为扫雷的进程名
            Text = "" + baseAddress;
            WriteMemory(baseAddress, 0);//设置地址值为0，本例子为扫雷计时值
        }
        catch(Exception ex) {
            MessageBox.Show(ex.Message );
        }

    }

    private void Form1_Load(object sender, EventArgs e)
    {
        timer1.Start();
    }

    private void timer1_Tick(object sender, EventArgs e)
    {

        try
        {

      
             baseAddress = 0x0100579C;
            // int.Parse(txtBaseAddress.Text.Trim());

            processName = txtProcessName.Text.Trim();

            processName = "winmine";
            Text = "" + baseAddress;
            Text =""+ ReadMemoryValue(baseAddress); 


        }

        catch {
        
        }
