泛型函数和类的C#问题 [英] C# problems with generic function and classes

问题描述

嗨.

简而言之，我收到一条错误消息:无法从T型转换为int或为double ......".
这是代码

Hi.

To be very brief, I get the error saying "cannot convert from type T to int, or to double ......"
here is the code

public class Class1<t>
{
    public Func<t> getter;

    public Class1(Func<t> getter)
    {
        this.getter = getter;
    }
}

public class Class2
{
    public Class1<bool> boolData;
    public Class1<int> intData;
    public Class1<long> longData;
    public Class1<float> floatData;
    public Class1<double> doubleData;
    public Class1<string> stringData;

}

public class Main
{
    public Class2 data;

    public void TryMe<t>(Func<t> getter)
    {
        if(typeof(T) == typeof(int))
        {
            data.intData = new Class1<int>(getter);
            // ABOVE LINE

        }
        else if(typeof(T) == typeof(double))
        {
            data.intData = new Class1<double>(getter);
        }
        // and so on for bool, long, float and string
    }
}

推荐答案

应用复制粘贴时，请确保更新所有相关项. ;)

data. int Data = new Class1< double >(getter);

您正在将class1 double 放入 int Data占位符.

When you apply copy-paste... be sure to update all relevant items. ;)

data.intData = new Class1<double>(getter);

You are putting a class1 double into the intData placeholder.
