如何在 C# 中使用反射显示方法和属性?

反射是描述代码中类型、方法和字段的元数据的过程。命名空间 System.Reflection 使您能够获取有关已加载程序集的数据，以及其中的元素(如类、方法和值类型)。System.Reflection 有许多类，但最常用的是 Assembly、AssemblyName、ConstructorInfo、MethodInfo、ParameterInfo、EventInfo、PropertyInfo 和 MemberInfo。
示例
static void Main(string[] args){
TypeInfo myType = typeof(TextInfo).GetTypeInfo();
IEnumerable<PropertyInfo> properties = myType.DeclaredProperties;
IEnumerable<MethodInfo> methods = myType.DeclaredMethods;
Console.WriteLine(myType);
Console.WriteLine(properties);
Console.WriteLine(methods);
StringBuilder strBuilder = new StringBuilder();
Console.WriteLine();
strBuilder.Append("The properties are:");
foreach (PropertyInfo p in properties){
strBuilder.Append("
" + p.Name);
}
strBuilder.Append("
");
strBuilder.Append("
The methods are:");
foreach (MethodInfo m in methods){
strBuilder.Append("
" + m.Name);
}
Console.WriteLine(strBuilder);
}
输出
System.Globalization.TextInfo System.Reflection.PropertyInfo[] System.Reflection.MethodInfo[] The properties are: Invariant ANSICodePage OEMCodePage MacCodePage EBCDICCodePage LCID CultureName IsReadOnly ListSeparator IsAsciiCasingSameAsInvariant IsRightToLeft The methods are: get_Invariant get_ANSICodePage get_OEMCodePage get_MacCodePage get_EBCDICCodePage get_LCID get_CultureName get_IsReadOnly get_ListSeparator set_ListSeparator get_IsAsciiCasingSameAsInvariant get_IsRightToLeft System.Runtime.Serialization.IDeserializationCallback.OnDeserialization Clone ReadOnly VerifyWritable SetReadOnlyState ToLower ToLower ChangeCase ChangeCaseToLower ChangeCaseToUpper ChangeCaseCommon ChangeCaseCommon ChangeCaseCommon ToLowerAsciiInvariant ToLowerAsciiInvariant ToUpperAsciiInvariant ToUpperAsciiInvariant ToLowerAsciiInvariant ToUpper ToUpper ToUpperAsciiInvariant IsAscii PopulateIsAsciiCasingSameAsInvariant Equals GetHashCode ToString ToTitleCase AddNonLetter AddTitlecaseLetter IsWordSeparator IsLetterCategory FinishInitialization ChangeCase IsInvariantLocale
