是否有可能通过一个静态方法来访问实例变量？ [英] Is it possible to access an instance variable via a static method?

问题描述

在C＃中，是否有可能通过在不同类别的静态方法来访问实例变量，而无需使用参数传递？

In C#, is it possible to access an instance variable via a static method in different classes without using parameter passing?

在我们的项目中，我有一个里面有很多的静态方法的数据访问层类。在这些方法中的SqlCommand 超时值已经硬codeD。在另一类（ DAC ）我们的框架中有哪些调用这些静态方法很多实例方法。

In our project, I have a Data access layer class which has a lot of static methods. In these methods the SqlCommand timeout value has been hard-coded. In another class(Dac) in our framework there are many instance methods which call these static methods.

我不想code过多使用参数的传递。你有任何其他的解决方案，这是比参数传递？

I don't want to code too much using parameter passing. Do you have any other solution which is easier than parameter passing?

推荐答案

是的，这可以从一个静态方法访问实例变量，而无需使用参数，但只有当你可以通过该声明为static的东西访问它。例如：

Yes, it is possible to access an instance variable from a static method without using a parameter but only if you can access it via something that is declared static. Example:

public class AnotherClass
{
    public int InstanceVariable = 42;
}

public class Program
{
    static AnotherClass x = new AnotherClass(); // This is static.

    static void Main(string[] args)
    {
        Console.WriteLine(x.InstanceVariable);
    }
}
