自定义.ToString之类的方法? [英] Custom .ToString like method??

问题描述

嗨
假设我有一个看起来像这样的课:

Hi
Let say I have a class which looks something like this:

public class MyClass
{
public static readonly string MyObject = "Myobj.ClientName";
}

我不会深入探讨事物为何如此发展……这就是我必须努力的方向.问题是，我只需要在''.''之后加上一点，所以我使用子字符串来获取''.''之后的所有字符串.在应用程序的其他地方，整个字符串都按原样使用.

我想以一种简单的形式来做.我想做这样的事情:

I''m not going to dive into why things are the way they are... this is what I have to work with. Thing is, I need only the bit after the ''.'' so I use substring to get all string after the ''.''. In other places in the application the entire string is used as is.

I want to do this in a simpler form. I want to do something like this:

MyClass.MyObject.ToShort();

因此，它将像.ToString一样工作，并且只返回特定的内容.

如何将.ToShort添加到类中?

任何帮助将不胜感激.
感谢

So it will work a lot like .ToString and only return something specific.

How can I add .ToShort to the class??

Any help would be appreciated.
Thanks

推荐答案

由于您使用的是.NET 3.5，因此有一种方法可以创建可用于字符串的扩展方法.在您的情况下，它将类似于:

Since you are using .NET 3.5, there is a way to create extension methods that can be used against strings. In your case it would be something like:

public static string ToShort(this string s)
{
    return s.Substring( 6 );
}

此处的键是参数中的this标识符.从此 [

The key here is the this identifier in the parameter. Code sample derived from this[^] article by Mike Gold.

嗨
您必须添加以下方法，如

Hi
you have to add following method like

public static string ToShort(string strsql)
{
   return "";
}

//you can access 
MyClass.ToShort(MyClass.MyObject);

是的，您可以添加ToShort，尝试对其进行编码.

如果您想

Yes you can add ToShort, try coding it.

you may also override ToString if you want to
