C# 反射获取类型信息教程

Type type = typeof(string);
Console.WriteLine(type.Name);        // 输出: String
Console.WriteLine(type.Namespace);   // 输出: System
Console.WriteLine(type.Assembly);    // 输出程序集信息

object obj = "Hello";
Type runtimeType = obj.GetType();
Console.WriteLine(runtimeType.FullName); // 输出: System.String

Type t = typeof(List);
MethodInfo[] methods = t.GetMethods();
PropertyInfo[] properties = t.GetProperties();
Console.WriteLine("方法列表：");
foreach (var m in methods)
{
Console.WriteLine($"- {m.ReturnType.Name} {m.Name}");
}
Console.WriteLine("属性列表：");
foreach (var p in properties)
{
Console.WriteLine($"- {p.PropertyType.Name} {p.Name}");
}

MethodInfo privateMethod = t.GetMethod("MyPrivateMethod", 
    BindingFlags.NonPublic | BindingFlags.Instance);

// 创建字符串数组实例
Type listType = typeof(List);
object listObj = Activator.CreateInstance(listType);
// 调用 Add 方法
MethodInfo addMethod = listType.GetMethod("Add");
addMethod.Invoke(listObj, new object[] { "hello" });
// 调用 Count 属性
PropertyInfo countProp = listType.GetProperty("Count");
int count = (int)countProp.GetValue(listObj);
Console.WriteLine(count); // 输出: 1
