推荐答案
Assembly assembly = Assembly.LoadFile(@"assembly location"); // you can change the way you load the assembly
Type type = assembly.GetType("mynamespace.NameOfTheClass");
ConstructorInfo constructor = type.GetConstructor(Type.EmptyTypes);
object classObject = constructor.Invoke(new object[] { });
MethodInfo methodInfo = type.GetMethod("GetDetails");
var returnValue = (List<customType>)methodInfo.Invoke(classObject, new object[] { param1});
根据您的类是否为静态以及您的构造函数是否接受任何参数,可能需要进行一些更改.
A few alterations might be required depending on if your class is static or not and if your constructor takes any parameters.
