Summary of 5 C # string manipulation methods sharing

This article mainly introduces the summary of the 5 C # string manipulation methods to share, this article explained that the string to be converted to List by separator, the string to follow, split into data, get array list comma-delimited string, get string length and other methods, need friends can refer to the

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

1. Convert string to List by separator

Split (Speater); foreach (var s in ss) {if (string). Isnullorwhitespace (s) | | s = = Speater. ToString (CultureInfo.InvariantCulture)) continue; var strval = s; if (toLower) {strval = S.tolower ();} list. ADD (Strval); } return list; }

2. The string to follow, split into data

3. Get array list comma-delimited string

<summary>///get array list comma-delimited string///</summary>///<param name= "list" ></param>///<param na Me= "Speater" ></param>///<returns></returns> public static string Getarraystr (list<string > list, String speater) {var sb = new StringBuilder (); for (var i = 0; i < list.) Count; i++) {if (i = = list. Count-1) {sb. Append (List[i]); } else {sb. Append (List[i]); Sb. Append (Speater); } return SB. ToString (); }

4. Get string length

<summary>///Get string length///</summary>///<param name= "inputstr" ></param>///<returns> </returns> public static int strlength (string inputstr) {var asc = new ASCIIEncoding (); var s = asc. GetBytes (INPUTSTR); Return S.sum (t => t = = 63? 2:1); }

5. Intercept the specified length string
