Question

我有一些字符串，我想订购内容。

string nr1 = "Number: 5 Specialty: Technology Role: Teacher";
string nr2 = "Specialty: Informatics Number: 1 Role: Student";
string nr3 = "Role: Teacher Specialty: Geography Number:10"

我想保留以下格式：“角色：X数字：Y专长：Z”；有办法吗？

RegEx方法通过解析所需的值

using System.Text.RegularExpressions;

string nr1 = "Number: 5 Specialty: Technology Role: Teacher";
var n1 = Regex.Match(nr1, "(?<=Number: )\\w+");
var s1 = Regex.Match(nr1, "(?<=Specialty: )\\w+");
var r1 = Regex.Match(nr1, "(?<=Role: )\\w+");

string result = string.Format("Role: {0} Number: {1} Speciality: {2}", r1, n1, s1);

有多种方法可以实现它，我通过将字符串转换为字符串列表来实现。我希望这可以帮助您。

string nr1 = "Number: 5 Specialty: Technology Role: Teacher"; 

List<string> stringAsList = nr1.Split(' ').ToList();

StringBuilder reorderedString = new StringBuilder();

int indexRole = stringAsList.FindIndex(x => x.Contains("Role:"));
int indexNumber = stringAsList.FindIndex(x => x.Contains("Number:"));
int indexSpeciality = stringAsList.FindIndex(x => x.Contains("Specialty:"));

reorderedString.Append($"Role: {stringAsList[indexRole + 1]} Number: {stringAsList[indexNumber + 1]} Speciality: {stringAsList[indexSpeciality + 1]}");

通过关键字订购字符串
