在类构造函数C＃中设置默认值 [英] set default value in class constructor C#

问题描述

我需要一个默认值集，并且需要访问和更新许多不同的页面。最初可以在类构造函数中设置默认值吗？在C＃.NET中执行此操作的正确方法是什么？

I need a default value set and many different pages access and update..initially can I set the default value in the class constructor like this? What is the proper way to do this in C# .NET?

public class ProfitVals
{

    private static double _hiprofit;

    public static Double HiProfit
    {
        get { return _hiprofit; }

        set { _hiprofit = value; }
    }

    // assign default value

    HiProfit = 0.09;

}

推荐答案

您可以将其放在声明中： private static double _hiprofit = 0.09;
或者，如果它是更复杂的初始化，则可以在静态构造函数中进行操作：

You can put it in the declaration: private static double _hiprofit = 0.09; Or if it's a more complicated initialization you can do it in the static constructor:

   private static double _hiprofit; 
   static ProfitVals() 
   {
      _hiprofit = 0.09;
   }

前者是首选，因为后者会产生性能损失： http://blogs.msdn.com/b/brada/archive/2004 /04/17/115300.aspx

The former is preferred as the latter pays a performance penalty: http://blogs.msdn.com/b/brada/archive/2004/04/17/115300.aspx
