如何检查两个GUID是否匹配？

使用以下C＃代码，如果g2与GUID具有相同的g1，如何匹配：

Guid g1 = new Guid("{10349469-c6f7-4061-b2ab-9fb4763aeaed}");
Guid g2 = new Guid("{45DF902E-2ECF-457A-BB0A-E04487F71D63}");

Answer 1

您使用Guid.Equals重载中的任何一个。

所以实际上：

Guid g1 = ...
Guid g2 = ...

if (g1.Equals(g2)) { /* guids are equal */ }

请注意，System.Guid也实现了相等运算符，因此以下内容也适用：

if (g1 == g2) { /* guids are equal */ }

Answer 2

ToString() GUID方法会导致字符串值一致，因此可以用来匹配。

检查this DotNetFiddle进行此测试。

using System;

public class Program
{
    public static void Main()
    {
        // Two distinct GUIDs
        Guid g1 = new Guid("{10349469-c6f7-4061-b2ab-9fb4763aeaed}");
        Guid g2 = new Guid("{45DF902E-2ECF-457A-BB0A-E04487F71D63}");       

        // GUID similar to 'g1' but with mixed case
        Guid g1a = new Guid("{10349469-c6f7-4061-b2ab-9fb4763AEAED}");

        // GUID similear to 'g1' but without braces
        Guid g1b = new Guid("10349469-c6f7-4061-b2ab-9fb4763AEAED");

        // Show string value of g1,g2 and g3
        Console.WriteLine("g1 as string: {0}\n", g1.ToString());
        Console.WriteLine("g2 as string: {0}\n", g2.ToString());
        Console.WriteLine("g1a as string: {0}\n", g1a.ToString());
        Console.WriteLine("g1b as string: {0}\n", g1b.ToString());

        // g1 to g1a match result
        bool resultA = (g1.ToString() == g1a.ToString());

        // g1 to g1b match result
        bool resultB = (g1.ToString() == g1b.ToString());

        // Show match result
        Console.WriteLine("g1 matches to g1a: {0}\n", resultA );
        Console.WriteLine("g1 matches to g1b: {0}", resultB );      
    }
}

输出

g1 as string：10349469-c6f7-4061-b2ab-9fb4763aeaed

g2 as string：45df902e-2ecf-457a-bb0a-e04487f71d63

g1a as string：10349469-c6f7-4061-b2ab-9fb4763aeaed

g1b as string：10349469-c6f7-4061-b2ab-9fb4763aeaed

g1与g1a匹配：True

g1与g1b匹配：True
