设置某程序随系统启动自动运行，取消自动运行。 使用到using Microsoft.Win32;名称空间。

public void SetAutoRun(string fileName, bool isAutoRun)   
{   
    RegistryKey reg = null;   
    try  
    {   
        if (!System.IO.File.Exists(fileName))   
        throw new Exception("该文件不存在!");   
        String name = fileName.Substring(fileName.LastIndexOf(@"") + 1);   
        reg = Registry.LocalMachine.OpenSubKey(@"SOFTWAREMicrosoftWindowsCurrentVersionRun", true);   
        if (reg == null)   
        reg = Registry.LocalMachine.CreateSubKey(@"SOFTWAREMicrosoftWindowsCurrentVersionRun");   
        if (isAutoRun)   
        reg.SetValue(name, fileName);   
        else  
        reg.SetValue(name, false); 
        MessageBox.Show("设定成功！","提示"); 
    }   
    catch  
    {   
        //throw new Exception(ex.ToString());   
    }   
    finally  
    {   
        if (reg != null)   
        reg.Close();   
    }   
 }
