用另一个部分类覆盖部分类的默认构造函数 [英] Override Default Constructor of Partial Class with Another Partial Class

问题描述

我不认为这是可能的，但如果是，那么我需要它:)

I don't think this is possible, but if is then I need it :)

我有一个来自 Visual Studio 2008 的 wsdl.exe 命令行工具自动生成的代理文件.

I have a auto-generated proxy file from the wsdl.exe command line tool by Visual Studio 2008.

代理输出是部分类.我想覆盖生成的默认构造函数.我宁愿不修改代码，因为它是自动生成的.

The proxy output is partial classes. I want to override the default constructor that is generated. I would rather not modify the code since it is auto-generated.

我尝试创建另一个部分类并重新定义默认构造函数，但这不起作用.然后我尝试使用 override 和 new 关键字，但这不起作用.

I tried making another partial class and redefining the default constructor, but that doesn't work. I then tried using the override and new keywords, but that doesn't work.

我知道我可以从部分类继承，但这意味着我必须更改我们所有的源代码以指向新的父类.我宁愿不必这样做.

I know I could inherit from the partial class, but that would mean I'd have to change all of our source code to point to the new parent class. I would rather not have to do this.

有什么想法、变通办法或技巧吗?

Any ideas, work arounds, or hacks?

//Auto-generated class
namespace MyNamespace {
   public partial class MyWebService : System.Web.Services.Protocols.SoapHttpClientProtocol {
      public MyWebService() {
         string myString = "auto-generated constructor";
         //other code...
      }
   }
}

//Manually created class in order to override the default constructor
namespace MyNamespace {
   public partial class MyWebService : System.Web.Services.Protocols.SoapHttpClientProtocol {
      public override MyWebService() { //this doesn't work
         string myString = "overridden constructor";
         //other code...
      }
   }
}

推荐答案

这是不可能的.部分类本质上是同一类的一部分；任何方法都不能被定义两次或被覆盖，包括构造函数.

This is not possible. Partial classes are essentially parts of the same class; no method can be defined twice or overridden, and that includes the constructor.

你可以在构造函数中调用一个方法，只在其他部分文件中实现它.

You could call a method in the constructor, and only implement it in the other part file.
