Static Constants in C#
提问by anonymous coward
I have this code;
我有这个代码；
using System;
namespace Rapido
{
class Constants
{
public static const string FrameworkName = "Rapido Framework";
}
}
Visual Studio tells me: The constant 'Rapido.Constants.FrameworkName' cannot be marked static
Visual Studio 告诉我： The constant 'Rapido.Constants.FrameworkName' cannot be marked static
How can I make this constant available from other classes without having to create a new instance of it? (ie. directly accessing it via Rapido.Constants.FrameworkName)
如何在不必创建它的新实例的情况下使其他类可以使用此常量？（即通过直接访问它Rapido.Constants.FrameworkName）

public static class Constants
{
public const string FrameworkName = "Rapido Framework";
}

A const is already static as it cannot change between instances.
const 已经是静态的，因为它不能在实例之间改变。

You don't need to declare it as static - public const string is enough.
您不需要将其声明为静态 - 公共常量字符串就足够了。
