C # string array each element is enclosed in single quotation marks, each of which is contained within the apostrophe

This kind of problem is often encountered when stitching SQL, especially when in query, the content is a single quote character

Strwhere + = "a.ec101_wrybh in (" + String. Join (",", codes. ToArray ()) + ")";
Codes is a list, which executes "a.ec101_wrybh in (a,b,c)"
String STRs = "1,2,3,4,5,6";
String s1= string. Format ("' {0} '", STRs. Replace (",", "', '"));

 string  S1 =  " 1,2,3,4,5,6   ;  string  s1_1 = S1. Replace (  , "   ); //  return Result: 1 ', ' 2 ', ' 3 ', ' 4 ', ' 5 ', ' 6  ' string  s2 = string . Format (  ' {0} '  , S1_1); //  replace {0} in ' {0} ' with 1 ', ' 2 ', ' 3 ', ' 4 ', ' 5 ', ' 6 ' So the result is what you want to achieve
