MRZ Parser c#控制台应用程序

Question

我试图从护照MRZ的名字，但我有困难，它的解析。我想知道名字。但是我得到了一个：-

System.ArgumentOutOfRangeException类型的未处理异常发生在mscorlib.dll中

每当我想知道名字的时候。

这里是我试图解析的地方

 if (string.IsNullOrEmpty(name) || name.Length < 44)
                { }

     var nameArraySplit = name.Substring(5).Split(new[] { "<<" }, StringSplitOptions.RemoveEmptyEntries);
      name =  nameArraySplit.Length >= 2 ? nameArraySplit[1].Replace("<", " ") : nameArraySplit[0].Replace("<", " ");

MRZ GBRTHATCHER0368447211111119718452091 1522044E12566123BUG<<<<<<<<<<<7 CAT<<GRUMPY<MINITE<<<<<<<<<<<<示例

谢谢

Answer 1

我想你可以在"<"上试试"<"而不是"<<"

然后得到nameArraySplit[2]

string name = "GBRTHATCHER03684472111111197184520911522044E12566123BUG<<<<<<<<<<<7CAT<<GRUMPY<MINITE<<<<<<<<<<<< ";

var nameArraySplit = name.Substring(5).Split(new[] {"<" }, StringSplitOptions.RemoveEmptyEntries);
name = nameArraySplit.Length >= 2 ? nameArraySplit[2] : nameArraySplit[0].Replace("<", " ");

string input = @"GBRTHATCHER03684472111111197184520911522044E12566123BUG<<<<<<<<<<<7CAT<<GRUMPY<MINITE<<<<<<<<<<<<";
string name = Regex.Match(input, @"(?i)([a-z]+)<[a-z]+<+?$").Groups[1].Value;
