In my last c# interview, I was asked to prove immutability of C# string,I know what is meant by immutability of c# string,But is it possible to prove immutability of c# string through code ? can i have a sample code snippet please. Thanks in advance I can prove that a string is not immutable. All I need to do is to show some code which mutates a string , like so: using System; using Syste
在我上一次的c＃访谈中， 我被要求证明C＃字符串的不变性，我知道c＃字符串的不变性是什么意思，但是有可能通过代码证明c＃字符串的不变性吗？ 我可以有一个示例代码片段吗？ 提前致谢 我可以证明一个string不是不可变的。 我需要做的就是显示一些代码，这些代码会改变string ，如下所示： using System; using System.Runtime.InteropServices; namespace Demo { class Program { static void Main(str
I'd like to create a generic method for converting any System.Enum derived type to its corresponding integer value, without casting and preferably without parsing a string. Eg, what I want is something like this: // Trivial example, not actually what I'm doing. class Converter { int ToInteger(System.Enum anEnum) { (int)anEnum; } } But this doesn't appear to work.
我想创建一个通用的方法，用于将任何System.Enum派生类型转换为相应的整型值，而无需强制转换并且最好不分析字符串。 例如，我想要的是这样的： // Trivial example, not actually what I'm doing. class Converter { int ToInteger(System.Enum anEnum) { (int)anEnum; } } 但是这似乎并不奏效。 Resharper报告说您不能将类型'System.Enum'的表达式转换为键入'int'。 现在我已经想
This question already has an answer here: Get int value from enum in C# 24 answers To get all values of the Enum try this var allValues = Enum.GetValues(typeof(TotalSteps)).Cast<int>().ToArray(); and your totalSteps property should look like this public int[] totalSteps { get { return Enum.GetValues(typeof(TotalSteps)).Cast<int>().ToArray(); } } how can I return it in "
这个问题在这里已经有了答案： 从C＃中的枚举中获得int值的24个答案 要获取Enum的所有值，请尝试此操作 var allValues = Enum.GetValues(typeof(TotalSteps)).Cast<int>().ToArray(); 你的totalSteps属性应该是这样的 public int[] totalSteps { get { return Enum.GetValues(typeof(TotalSteps)).Cast<int>().ToArray(); } } 我怎样才能在“get”函数中返回它？ 该值无法转换 属性（我猜）被定义为获取
This question already has an answer here: Get int value from enum in C# 24 answers Just cast the enum value to int . A a = new A(); int k = (int)a.NumberOfFiscalPeriod; The inverse is valid too, even if there is no enum value defined for that int value, for sample: int i = 13; // int value EFiscalPeriond f = (EFiscalPeriond) i; // converting int to enum
这个问题在这里已经有了答案： 从C＃中的枚举中获得int值的24个答案 只需将枚举值转换为int 。 A a = new A(); int k = (int)a.NumberOfFiscalPeriod; 即使没有为该int值定义的枚举值，反例也是有效的，对于示例： int i = 13; // int value EFiscalPeriond f = (EFiscalPeriond) i; // converting int to enum

Therefore I use enumerate. enum Status : int { Stack = 1, Overflow = 2, StackOverflow = 3 } But when I want to get value of Stack, I get "Stack" . int status = 0; status = Status.Stack; //I want to assign 1 to status but Status.

This question already has an answer here: Get int value from enum in C# 24 answers In addition to @dtb You can specify the int (or flag) of your enum by supplying it after the equals sign. enum MyEnum { Foo = 0, Bar = 100, Baz = 9999 } Cheers If you have an enum such as enum MyEnum { Foo, Bar, Baz, } and a value of that enum such as MyEnum value = MyEnum.Foo;
这个问题在这里已经有了答案： 从C＃中的枚举中获得int值的24个答案 除了@dtb 您可以通过在等号后面提供枚举来指定枚举的int（或标志）。 enum MyEnum { Foo = 0, Bar = 100, Baz = 9999 } 干杯 如果你有一个枚举类型如 enum MyEnum { Foo, Bar, Baz, } 以及该枚举的值，如 MyEnum value = MyEnum.Foo; 那么将该值转换为int的最佳方式是 int result = (int)value; 我会在Enum上以扩展方法
This question already has an answer here: Get int value from enum in C# 24 answers To answer your question "how can I get the integer for string value": To convert from a string into an enum, and then convert the resulting enum to an int, you can do this: public enum Animals { dog = 0, cat = 1, rat = 2 } ...
