从C＃中的列表获取通用类

Question

How can I loop through and get generic class from a list in c#. My code is like this.

private void processList()
{
    List<CommandParameter> parameters = new List<CommandParameter>();
    parameters.Add(new CommandParameter<string>("a", "c", "a"));
    parameters.Add(new CommandParameter<int>("a", "c", 1));

    foreach (var parameter in parameters)
    {
        // How can I loop through the parameters list and get the generic class
    }
}

Is this possible? Can anyone tell me how to solve this?

this is command parameter classes

public class CommandParameter<T> : CommandParameter{
    public string Str { get; private set; }
    public string TypeName { get;private  set; }
    public T TypeValue { get; private set; }

    public CommandParameter(string s, string typeName, T typeValue) {
        Str = s;
        TypeName  = typeName;
        TypeValue = typeValue;
    }
}

public abstract class CommandParameter {

}

Assuming that you are looking for the generic argument's, here is an example:

List<IEnumerable> coll = new List<IEnumerable>();

coll.Add(new List<string> { "a", "b" });
coll.Add(new List<int> { 7 });

foreach (var item in coll)
{
    var args = item.GetType().GetGenericArguments();
    foreach (var genericArg in args)
    {
        Console.WriteLine(genericArg); // generic types (e.g. string, int)
    }
}
