在C＃构造函数的参数名称 [英] Name of the constructor arguments in c#

问题描述

我在，我需要得到构造函数的变量的名称在我班上的要求。
我想它使用C＃反射，但constructorinfo不给足够的信息。因为它仅提供了参数的数据类型，但我想的名字，前

I've a requirement in which i need to get the variables names of the constructor in my class. I tried it using c# reflection, but constructorinfo does not give sufficient information. As it only provides the datatype of the parameters but i want the names, ex

Class a
{    
    public a(int iArg, string strArg)
    {
    }
}

现在我想iArg和strArg

Now i want "iArg" and "strArg"

感谢

推荐答案

如果你调用 ConstructorInfo.GetParameters（），那么你会得到的ParameterInfo 对象，其中有一个名称包含参数的name属性。

If you call ConstructorInfo.GetParameters(), then you will get back an array of ParameterInfo objects, which has a Name property containing the name of the parameter.

请参阅this MSDN页面的更多信息和示例。

See this MSDN page for more information and a sample.

有关A类的构造函数的每个参数下面的示例打印的信息：

The following sample prints information about each parameter of class A's constructor:

public class A
{
    public A(int iArg, string strArg)
    {
    }
}

....

public void PrintParameters()
{
    var ctors = typeof(A).GetConstructors();
    // assuming class A has only one constructor
    var ctor = ctors[0];
    foreach (var param in ctor.GetParameters())
    {
        Console.WriteLine(string.Format(
            "Param {0} is named {1} and is of type {2}",
            param.Position, param.Name, param.ParameterType));
    }
}

以上样本打印：

The above sample prints:

Param 0 is named iArg and is of type System.Int32
Param 1 is named strArg and is of type System.String
