獲取 Guid 的字串表示

可以使用內建的 ToString 方法獲得 Guid 的字串表示

string myGuidString = myGuid.ToString();

根據你的需要，你還可以通過向 ToString 呼叫新增格式型別引數來格式化 Guid。

var guid = new Guid("7febf16f-651b-43b0-a5e3-0da8da49e90d");

// None          "7febf16f651b43b0a5e30da8da49e90d"
Console.WriteLine(guid.ToString("N"));

// Hyphens       "7febf16f-651b-43b0-a5e3-0da8da49e90d"
Console.WriteLine(guid.ToString("D"));

// Braces        "{7febf16f-651b-43b0-a5e3-0da8da49e90d}"
Console.WriteLine(guid.ToString("B"));

// Parentheses   "(7febf16f-651b-43b0-a5e3-0da8da49e90d)"
Console.WriteLine(guid.ToString("P"));

// Hex           "{0x7febf16f,0x651b,0x43b0{0xa5,0xe3,0x0d,0xa8,0xda,0x49,0xe9,0x0d}}"
Console.WriteLine(guid.ToString("X"));
