c# - 在c#中将动态对象转换为动态类型的数组

Question

我有两种类型:

    public class Type1
    {
        public string Name { get; set; }
    }

    public class Type2
    {
        public string Name { get; set; }
    }

我有一个元素列表(每个元素都是一个对象类型)。一些元素可以是一个数组。 (数组可以是 type1[] 或 type2[])

我的目标是:
1-迭代我的元素列表
2-确定哪些是 type1[]array pr type2[] array
3-获取先前数组元素的名称值属性

这就是我所做的:

    foreach (var Myobject in MyList)
    {
        if (myObject.GetType().IsArray)
        {
            var elementType = myObject.GetType().GetElementType()// should me return the element type, ie Type1 or Type2

            //This is where I am stuck, I know that my object is an array but I cannot cast if in type1[] or type2[] array by using elementType
            //The following is not working
            elementType[] myArrat = (elementType[])myObject;

            // And I don't want to hardwrite each case for each possible type like this :
            Type1[] myArrat = (Type1[])myObject;
            Type2[] myArrat = (Type2[])myObject;
            // I want to use the elementType that I got previously

        }
    }

预先感谢您的帮助。

你不能做你想做的事。坦率地说，您可能也不需要这样做。如果您期望不同的类型，则意味着您将对每种类型执行不同的操作。您可以做的是更改 Type1 和 Type2 以扩展相同的基类并改用基类:

public class TypeBase 
{
   public virtual string Name { get; set; }
}

public class Type1 : TypeBase
{
}

public class Type2 : TypeBase
{
}


foreach (var myobject in MyList)
{
    if (myObject.GetType().IsArray)
    {
        object[] array = (object[]) myObject;
        TypeBase[] yourArray = array.Cast<TypeBase>();
        //use the properties and methods of TypeBase instead of Type1 and Type2
        //mark the methods and properties in TypeBase as virtual and
        //override them on Type1 and Type2 if needed
    }
}
