第一步:引用空间
//系统默认空间添加
using System;
//添加对注册表操作所需引用空间
using Microsoft.Win32;

第二步:添加函数

//检测目标机器上是否安装Microsoft .NETFramework 1.1平台
  public bool DoesDotNETFrameworkExist(string  udeVersion)
  {
   bool ExistFlag=false;   
   RegistryKey hkml = Registry.LocalMachine;
   RegistryKey mySubKey1 = hkml.OpenSubKey("SOFTWARE",true);
   RegistryKey mySubKey2 = mySubKey1.OpenSubKey("Microsoft",true);
   string[] myKeyNames1= mySubKey2.GetSubKeyNames();
   foreach(string tempKey1 in myKeyNames1)
   {
    if(tempKey1 == ".NETFramework")
    { 
     RegistryKey mySubKey3 = mySubKey2.OpenSubKey(".NETFramework",true);
     string[] myKeyNames2= mySubKey3.GetSubKeyNames();
     foreach(string tempKey2 in myKeyNames2)
     {       
      if(tempKey2 == "policy")
      {
       RegistryKey mySubKey4 = mySubKey3.OpenSubKey("policy",true);
       string[] myKeyNames3= mySubKey4.GetSubKeyNames();
       foreach(string tempKey3 in myKeyNames3)
       {         
        if(tempKey3 == "v1.1")
        {
         MessageBox.Show(tempKey3);
         ExistFlag=true;
         break;
        }
       }
       break;
      }
     }     
     break;
    }
   }
   return ExistFlag;
  }
