TryParse<TEnum>(String, Boolean, TEnum) 方法嘗試將具名常數的字串表示轉換成其對等列舉值時,會使用不區分大小寫的比較。 C# 複製 執行 using System; [Flags] enum Colors { None=0, Red = 1, Green = 2, Blue = 4 }; public class Example { public static void Main() { string[] color...
在C#中,你可以使用Enum.Parse方法或Enum.TryParse方法来将字符串转换为枚举。以下是两种方法的示例代码: 使用Enum.Parse csharp using System; namespace StringToEnumExample { enum Color { Red, Green, Blue } class Program {static void Main() { string color = "Red"; if (Enum.IsDefined(typeof(Colo...
// 字符串转枚举 Enum.TryParse("Tuesday", out Days bar); // true, bar = Days.Tuesday (Days)Enum.Parse(typeof(Days), "Tuesday"); // Days.Tuesday // 枚举转数字 byte foo = (byte)Days.Monday; // 1 // 数字转枚举 Days foo = (Days)2; // Days.Tuesday // 获取枚举所属的数字类型...
}// The example displays the following output:// Converted -3 to Unknown// Converted -1 to Late// Converted 0 to OnTime// Converted 1 to Early// Converted 5 to Unknown// Converted 2,147,483,647 to Unknown Parse和TryParse方法允许将枚举值的字符串表示形式转换为该值。字符串表示形式可以是...
Enum.TryParse("Active", out StatusEnum myStatus); 这也包括C#7的新内联out变量,因此它执行try-parse、转换为显式枚举类型并初始化+填充myStatus变量。 如果您可以访问C#7和最新的.NET,则这是最佳方法。 在.NET中,这相当丑陋(直到4或以上版本): StatusEnum MyStatus = (StatusEnum) Enum.Parse(typeof(...
Parse和TryParse方法允许将枚举值的字符串表示形式转换为该值。字符串表示形式可以是枚举常量的名称或基础值。 string number = "-1"; string name = "Early"; try { ArrivalStatus status1 = (ArrivalStatus) Enum.Parse(typeof(ArrivalStatus), number); ...

TryParse<TEnum>(String, Boolean, TEnum%)Converts the string representation of the name or numeric value of one or more enumerated constants to an equivalent enumerated object. A parameter specifies whether the operation is case-sensitive. The return value indicates whether the conversion succeeded....

What it is explain that the integer value expressed as base 2 must be as shown (for four values in the above example): 00001 00010 00100 01000 . Expressed in base 10, this is 1, 2, 4, 8. Difference : You can see the difference lies in the Enum.ToString() method. If your enum ...
