< experience >c#/. NET string manipulation methods Summary

String manipulation is the most basic, most common, and most commonly used in C #, and I've summarized several common methods below.

1. Convert strings to List by delimiter

        /// <summary>          ///Convert a string to a List by delimiter/// </summary>          /// <param name= "str" >Source String</param>          /// <param name= "Speater" >Separators</param>          /// <param name= "ToLower" >Convert to lowercase</param>          /// <returns></returns>           Public Staticlist<string> Getstrarray (stringStrCharSpeater,BOOLtoLower) {            varList =Newlist<string>(); varSS =Str.            Split (Speater); foreach(varSinchSS) {                if(string. Isnullorwhitespace (s) | | s = = Speater. ToString (CultureInfo.InvariantCulture))Continue; varStrval =s; if(toLower) {Strval=S.tolower (); } list.            ADD (Strval); }            returnlist; }

2. Change the string to the data

        /// <summary>          ///Turn a string into a data partition/// </summary>          /// <param name= "str" ></param>          /// <returns></returns>           Public Static string[] Getstrarray (stringstr) {            returnStr. Split (New[] {',',',' }); }

3. Get the comma-delimited string for the array list

        /// <summary>        ///get a comma-delimited string of array lists/// </summary>        /// <param name= "list" ></param>        /// <param name= "Speater" ></param>        /// <returns></returns>         Public Static stringGetarraystr (list<string> list,stringspeater) {            varSB =NewStringBuilder ();  for(vari =0; I < list. Count; i++)            {                if(i = = list.) Count-1) {sb.                Append (List[i]); }                Else{sb.                    Append (List[i]); Sb.                Append (Speater); }            }            returnsb.        ToString (); }

4. Get the string length

        /// <summary>        ///Get string length/// </summary>        /// <param name= "Inputstr" ></param>        /// <returns></returns>         Public Static intStrlength (stringinputstr) {            varASC =Newasciiencoding (); vars =ASC.            GetBytes (INPUTSTR); returnS.sum (t = = T = = the?2:1); }

5. Intercept a specified length string

        /// <summary>        ///intercepts a specified length string/// </summary>        /// <param name= "inputstring" ></param>        /// <param name= "Len" ></param>        /// <returns></returns>         Public Static stringCUTSTR (stringInputString,intLen) {            varIsshowfix =false; if(Len%2==1) {Isshowfix=true; Len--; }            varASCII =Newasciiencoding (); varTemplen =0; varTempString =""; vars =ASCII.            GetBytes (inputstring);  for(vari =0; i < s.length; i++) {Templen+ = S[i] = = the?2:1; Try{tempstring+ = Inputstring.substring (i,1); }                Catch                {                     Break; }                if(Templen >len) Break; }            varMyByte =Encoding.Default.GetBytes (inputstring); if(Isshowfix && MyByte. Length >len) tempstring+="... .."; returntempstring; }

For the time being, there are five ways.
