Question

我有不同的选择如何将我的GUID存储为字符串行。

1. Accessibility|5102d73a-1b0b-4461-93cd-0c024738c19e
2. 5102d73a-1b0b-4461-93cd-0c024738c19e;#5102d73a-1b0b-4461-93cd-0c024733d52d
3. |;#5102d73a-1b0b-4461-93cd-0c024738c19e;#SharePointTag|5102d73a-1b0b-4461-93cd-0c024733d52d
3. Business pages|;#5102d73a-1b0b-4461-93cd-0c024738cz13;#SharePointTag|5102d73a-1b0b-4461-93cd-0c024733d52d

你能帮助我解决这个问题吗？我怎么能解析这个标签并最终得到Guids类型？也许正则表达可以帮助这种情况？

Answer 1

看起来您正在玩托管元数据，期限商店ID和字词集ID：）

只需使用常规正则表达式（下面的“p”变量）：

string c1 = "Accessibility|5102d73a-1b0b-4461-93cd-0c024738c19e";
string c2 = "5102d73a-1b0b-4461-93cd-0c024738c19e;#5102d73a-1b0b-4461-93cd-0c024733d52d";
string c3 = "|;#5102d73a-1b0b-4461-93cd-0c024738c19e;#SharePointTag|5102d73a-1b0b-4461-93cd-0c024733d52d";
string c4 = "Business pages|;#5102d73a-1b0b-4461-93cd-0c024738cz13;#SharePointTag|5102d73a-1b0b-4461-93cd-0c024733d52d";
string p = @"([a-zA-Z0-9]{8}[-][a-zA-Z0-9]{4}[-][a-zA-Z0-9]{4}[-][a-zA-Z0-9]{4}[-][a-zA-Z0-9]{12})";

MatchCollection mc;

Console.WriteLine("#1");
mc = Regex.Matches(c1, p);
foreach (var id in mc)
    Console.WriteLine(id);

Console.WriteLine("#2");
mc = Regex.Matches(c2, p);
foreach (var id in mc)
    Console.WriteLine(id);

Console.WriteLine("#3");
mc = Regex.Matches(c3, p);
foreach (var id in mc)
    Console.WriteLine(id);

Console.WriteLine("#4");
mc = Regex.Matches(c4, p);
foreach (var id in mc)
    Console.WriteLine(id);

输出：

#1
5102d73a-1b0b-4461-93cd-0c024738c19e
#2
5102d73a-1b0b-4461-93cd-0c024738c19e
5102d73a-1b0b-4461-93cd-0c024733d52d
#3
5102d73a-1b0b-4461-93cd-0c024738c19e
5102d73a-1b0b-4461-93cd-0c024733d52d
#4
5102d73a-1b0b-4461-93cd-0c024738cz13

Answer 2

var possibleGuids = myString.Split("|;#".ToCharArray(), 
                                   StringSplitOptions.RemoveEmptyEntries);
Guid g;
foreach(var poss in possibleGuids)
{
  if(Guid.TryParse(poss, out g))
  {
      // g contains a guid!
  }
}

Answer 3

string sContent = "your data"; // any of your four forms of input
string sPattern = @"([a-z0-9]*[-]){4}[a-z0-9]*";

MatchCollection mc = Regex.Matches(sContent, sPattern );

foreach (var sGUID in mc)
{
    // Do whatever with sGUID
}

Answer 4

您可以拆分字符串，例如

 "fist|second".Split('|')

您获得GUID字符串后，使用

将其转换为GUID

 Guid = new Guid(myString);

第一行

var guid = new Guid("Accessibility|5102d73a-1b0b-4461-93cd-0c024738c19e".Split("|")[1]);

第二行

var myArray = "5102d73a-1b0b-4461-93cd-0c024738c19e;#5102d73a-1b0b-4461-93cd-0c024733d52d".Split(';');
var guid1 = new Guid(myArray[0]);
var guid2 = new Guid(myArray[1].Replace('#',''));

所以你可以这样继续......
