C# 大于等于转换数学区间

代码：

 1 public static string Trans_version(string simver)  2         {  3             var sarry = simver.Split(' ');  4             string TransVersion = ;  5             if (sarry.Length == 2)  6             {  7                 switch (sarry[0])  8                 {  9                     case >=: TransVersion = [ + sarry[1] + ,); break; 10                     case >: TransVersion = ( + sarry[1] + ,); break; 11                     case ==: TransVersion = [ + sarry[1] + ]; break; 12                     case <=: TransVersion = (, + sarry[1] + ]; break; 13                     case <: TransVersion = (, + sarry[1] + ); break; 14                 } 15             } 16             else 17             { 18                 switch (sarry[0]) 19                 { 20                     case >=: TransVersion = [+sarry[1]+, ; break; 21                     case >: TransVersion = (+sarry[1] + ,; break; 22                 } 23                 switch (sarry[2]) 24                 { 25                     case <=: TransVersion += sarry[3] + ]; break; 26                     case <: TransVersion +=sarry[3] + ); break; 27                 } 28                  29             } 30             return TransVersion; 31         }
