C# vs2010 .net framework 4 工程转 vs2005工程 .net framework2 （一）

当前正在做的一个项目，原来使用vs2010 .net framework4.0 C#做的界面，但是最近客户要求支持windows 2000 server。顿时大家都傻眼了。没办法，客户是大爷呀。在网上搜了半天，只发现哭爹喊娘要方法的，没看到什么好的解决办法。还是自己动手吧。整个过程可以说是一波三折。

首先尝试的方法是把vs2010工程的Target framework设置成.net framework2.0；编译通过但是不能运行；

接着把上面的工程修改成2005工程；编译通过但还是不能运行；

最后在windows2000下安装vs2005，调试运行，发现最后问题之所在，最终完成程序的迁移。

为了方便弟兄们检索，文中列出了详细的编译错误。另外上述三步放到三篇文章里面，方便阅读。

 

最初想法：windows 2000 不是支持.net framework2.0吗，把当前工程的目标Target framework设置成.net framework2.0不就行了吗。以下简述修改过程：

1 重新编译，错误如下：

2 做如下修改

（1）Solution Explorer下  找到References ，“Remove”下面各项（图标显示了黄色！号）

Microsoft.CSharp

System.Core

System.Data.DataSetExtensions

System.Runtim.Serialization

Sysem.ServiceModel

System.Xml.Ling

（2）Solution Explorer下  找到Property，双击“Resources.resx”

       Resources.resx下切换到images分类，所有image删掉，重新添加。注意名称必须一致。

（3） 重新编译。错误如下：

3  做如下修改：

（1）注掉所有“using System.Linq;”    

（2）service下所有web service删除，重新导入； 

 （3）修改所有webservice调用方式；以下示例

原来的：

LoginServicePortTypeClient remoteLogin;

remoteLogin = new LoginServicePortTypeClient("LoginServiceHttpSoap12Endpoint", remoteaddress);

userinforv = remoteLogin.login(param);

现在的：

Company.LoginService.LoginService loginService = new Company.LoginService.LoginService();

loginService.Url = remoteaddress;

userinforv = loginService.login(param);

（4）重新编译，错误如下：

            Dictionary<String, List<MFileInfo>>.KeyCollection keyColl = tasks.Keys;

            foreach (string s in keyColl)

5 做如下修改：

通过手工的方法实现IntPtr的偏移

ptr.Ptr = m.LParam;                       

 IntPtr intPtrFilePath = new IntPtr(m.LParam.ToInt32() + 4);

  //String filename = Marshal.PtrToStringAuto(ptr.Ptr + 4); // PtrToStringUni

  String filename = Marshal.PtrToStringAuto(intPtrFilePath); // PtrToStringUni

 

至此编译通过，但是实验结果如下：

在安装了.net framework3.5sp1的机器上工作正常。(实际上此FX包含3.5，3.0，2.0)

在windows2000下，在安装了FX2.0后，程序不能启动，双击没什么反应。由于2000下不能安装FX3.5，FX3.0，只好实验在vs2005下编译此项目。
