How can you get the names of method parameters?
提问by Luke Foust
If I have a method such as:
如果我有一个方法，例如：
public void MyMethod(int arg1, string arg2)
How would I go about getting the actual names of the arguments? I can't seem to find anything in the MethodInfo which will actually give me the name of the parameter.
我将如何获取参数的实际名称？我似乎无法在 MethodInfo 中找到任何实际上会给我参数名称的内容。
I would like to write a method which looks like this:
我想写一个看起来像这样的方法：
public static string GetParamName(MethodInfo method, int index)
So if I called this method with:
因此，如果我使用以下命令调用此方法：
string name = GetParamName(MyMethod, 0)
it would return "arg1". Is this possible?
它会返回“arg1”。这可能吗？
采纳答案by Tom Anderson
public static string GetParamName(System.Reflection.MethodInfo method, int index)
{
string retVal = string.Empty;
if (method != null && method.GetParameters().Length > index)
retVal = method.GetParameters()[index].Name;
return retVal;
}
The above sample should do what you need.
上面的示例应该可以满足您的需求。

Try something like this:
尝试这样的事情：
foreach(ParameterInfo pParameter in pMethod.GetParameters())
{
//Position of parameter in method
pParameter.Position;
//Name of parameter type
pParameter.ParameterType.Name;
//Name of parameter
pParameter.Name;
}

without any kind of error checking:
没有任何错误检查：
public static string GetParameterName ( Delegate method , int index )
{
return method.Method.GetParameters ( ) [ index ].Name ;
}
You could use 'Func<TResult>' and derivatives to make this work for most situations
您可以使用 'Func<TResult>' 和导数来使其适用于大多数情况

nameof(arg1)will return the name of the variable arg1
nameof(arg1)将返回变量的名称 arg1
