比较数据类型，C＃中的值

本文介绍了比较数据类型，C＃中的值的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我想比较两个类的数据类型并返回bool值。问题是我的方法不比较类中的类值 这是代码： public static class 比较 { public static bool PublicInstancePropertiesEqual< T>（ this T self，T to， params string [] ignore）其中 T： class { if （self！= null && to ！= null ） { var type = typeof运算（T）; var ignoreList = new List< string>（ignore）; var unequalProperties = 来自 pi in type.GetProperties（BindingFlags.Public | BindingFlags.Instance） where ！ignoreList.Contains（pi.Name） 让 selfValue = type.GetProperty（pi.Name）.GetValue（self， null ） 让 toValue = type.GetProperty（pi.Name）.GetValue（to， null ） 其中 selfValue！= toValue&& （selfValue == null ||！PublicInstancePropertiesEqual（selfValue，toValue，ignore）） select selfValue; return ！unequalProperties.Any（）; } return self == to; } } 这里是比较： private void Form1_Load（ object sender，EventArgs e） { Obj1 obj1 = new Obj1（）; Obj1 obj11 = new Obj1（）; Obj2 obj2 = new Obj2（）; Obj2 obj22 = new Obj2（）; obj1.param1 = 1; obj1.param2 = 2; obj2.param3 = 3; obj1.obj2 = obj2; obj11.param1 = 1; obj11.param2 = 2; obj22.param3 = 4; obj11.obj2 = obj22; bool res = Compare.PublicInstancePropertiesEqual（obj1，obj11，（ 安全））; } } class Obj1 { public string param1 { get ; set ; } public string param2 { get ; set ; } public Obj2 obj2 { get ; set ; } } class Obj2 { public string param3 { get ; set ; } public decimal param4 { get ; set ; } } 即使参数值发生变化，返回值也为真。 div class =h2_lin>解决方案 I'd like to compare the data types of two classes and return bool values. The problem is my method doesn't compare values inside class of a classHere is the code:public static class Compare{ public static bool PublicInstancePropertiesEqual<T>(this T self, T to, params string[] ignore) where T : class { if (self != null && to != null) { var type = typeof(T); var ignoreList = new List<string>(ignore); var unequalProperties = from pi in type.GetProperties(BindingFlags.Public | BindingFlags.Instance) where !ignoreList.Contains(pi.Name) let selfValue = type.GetProperty(pi.Name).GetValue(self, null) let toValue = type.GetProperty(pi.Name).GetValue(to, null) where selfValue != toValue && (selfValue == null || !PublicInstancePropertiesEqual(selfValue, toValue, ignore)) select selfValue; return !unequalProperties.Any(); } return self == to; }}And here is the comparison:private void Form1_Load(object sender, EventArgs e) { Obj1 obj1 = new Obj1(); Obj1 obj11 = new Obj1(); Obj2 obj2 = new Obj2(); Obj2 obj22 = new Obj2(); obj1.param1 = "1"; obj1.param2 = "2"; obj2.param3 = "3"; obj1.obj2 = obj2; obj11.param1 = "1"; obj11.param2 = "2"; obj22.param3 = "4"; obj11.obj2 = obj22; bool res = Compare.PublicInstancePropertiesEqual(obj1, obj11, ("secure")); }}class Obj1{ public string param1 { get; set; } public string param2 { get; set; } public Obj2 obj2 { get; set; }}class Obj2{ public string param3 { get; set; } public decimal param4 { get; set; }}The returned value is res is true even when the values of the parameters change. 解决方案 这篇关于比较数据类型，C＃中的值的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
