Question

我正在尝试创建一个泛型方法，我必须将一些字符串附加到Generic数据类型并创建该附加字符串的实例。

例如：我有两节课 Object1，对象2， Object3， Object4，.... Object100和 Object1Address， Object2Address， Object3Address， Object4Address，.... Object100Address

现在我有方法为每个对象，如MethodObject1（），MethodObject2（），MethodObject3（），MethodObject4（）

MethodObject1()
{
     Object1 object = new Object1();
     Object1Address objectAddress = new Object1Address();

     TestMethod();
}

MethodObject2()
{
     Object2 object = new Object2();
     Object2Address objectAddress = new Object2Address();

     TestMethod();
}

MethodObject3()
{
     Object3 object = new Object3();
     Object3Address objectAddress = new Object3Address();

     TestMethod();
}

MethodObject4()
{
     Object4 object = new Object4();
     Object4Address objectAddress = new Object4Address();

     TestMethod();
}
.
.
.
MethodObject100()
{
     Object100 object = new Object100();
     Object100Address objectAddress = new Object100Address();

     TestMethod();
}

但是大约有100个对象，所以我必须以类似的方式创建100个方法。所以我想到了创建一个通用方法。

There is a method which returns only the an array of Object name from an XML file.
Eg: ObjectName[] objectName = GetObjects(); // Returns an array of Object Names from XML file so that 

objectName[0] = Object1;
objectName[1] = Object2;
objectName[2] = Object3;
objectNmae[3] = Object4;
.
.
.
objectName[99] = Object100;

I am looping through objectName array
foreach(var objectItem in objectName)
{
    MethodName<objectItem>();
}

In my generic method I can create an instance of object, like
MethodName<T>()
{
   T t = new T();
   Some how I have to get the name of T and append Address to T 
   So that I can create TAddress instance like
   TAddress tAddress = new TAddress();

}

有什么方法可以用C sharp做到这一点吗？

您的案例并不需要通用方法。

您可能希望覆盖类中的ToString方法。

class PersonAddress()
{
    public override string ToString()
    {
        return string.Concat(this.Street, ", ",  this.City, ", ", this.Postcode);
    }
}

class Person()
{
    public override string ToString()
    {
        return string.Concat(this.Name, ", ",  this.PersonAddress.ToString());
    }
}

请注意Person类如何重用PersonAddress.ToString()方法。

即使进行了编辑，我仍然无法按照您的要求进行操作。然而，为了推动前进，我将提供一个至少可以帮助你理解你想要的答案。

public class ThingWithAddress<T>
{
    public T Item { get; private set; }
    public string Address { get; private set; }

    public static ThingWithAddress<T> Create(T item, string address)
    {
        return new ThingWithAddress<T>
        {
            Item = item,
            Address = address,
        };
    }
}

然后你可以得到一个既有人又有地址的对象：

Person person = ...;
var personWithAddress = ThingWithAddress.Create(person, "some address");

不要采取错误的方式，但你可能需要学习足够的C＃以形成一个好问题，因为就目前而言，问题似乎令人困惑和不一致。
