如何返回引用类型c#int [英] how to return a reference type c# int

问题描述

我试图返回一个C#引用类型，以便我可以在该类之外编辑值:(有点像Java Integer引用类型)

到目前为止，我想到的是:

i am trying to return a c# reference type so i can edit the value outside of the class:(kinda like how the java Integer reference type)

what i came up with so far are as follows:

public class test
{
    int i;
    public Object get()
    {
        return i;
    }
}

public void program()
{
    test t = new test();

    t.get() = 1;
}

我在代码中下划线的地方是有错误的地方.

有人知道吗?

the place which i underline in the code is where there is a error.

anyone know how?

推荐答案

尝试以下操作:

public class test
{
    int i;
    public int I
    {
        get{ return i; }
        set{ i = value; }
    }
}
 
public void program()
{
    test t = new test();
 
    t.I = 1;
}

您的代码存在的问题是您无法设置函数.您必须同时使用get和set的属性.然后，您可以创建对象的新实例(在本例中为TestClass)并设置其属性的值.

Problem with your code is that you cant set a function. You have to use a property with both get and set. Then you can create a new instance of your object (in this case TestClass) and set the value of it''s properties.

public class TestClass
{
    public int MyNumericValue {get; set; }
}

public void program()
{
    test t = new TestClass();
    t.MyNumericValue  = 8;

   Console.WriteLine(t.MyNumericValue); // Will return 8
}
