如何从字符串“ string []”中获取.NET数组类型？ [英] How to get .NET array type from the string "string[]"?

问题描述

给出字符串 string [] ，并要求获取该类的基础类型，可能以以下内容开头：

Given the string "string[]" and asked to get the underlying Type for this class, one might start with:

private Type getTypeByName(string typeName)
{
    if (typeName.EndsWith("[]"))
    {
           return something; // But what? 
    }

    return Type.GetType(typeName);
}

string []是什么类型，如何反映出该类型

What type is "string[]" and how does one reflect the type out of it?

显然有一个 System.String 类型和一个 System.Array 类型，但我看不到它们如何像在 Nullable< T> 及其T与 MakeGenericType 方法。

Obviously there's a System.String type and a System.Array type, but I can't see how they can be reflected "together" as you would normally do for Nullable<T> and its T with the MakeGenericType method.

任何帮助打破我陷入困境的思路的人，将不胜感激！

Any help to break the mind-loop I've gotten myself into will be greatly appreciated!

推荐答案

究竟是什么问题？ Type.GetType 可以正常工作：

What exactly is your problem? Type.GetType works fine:

Console.WriteLine(typeof(string[]));
var type = Type.GetType("System.String[]");
Console.WriteLine(type);

打印：

System.String[]
System.String[]

这按预期工作。
