Some String Functions Of C#

In this article, I am going to share some string functions of C# with the help of example. In the c# there are a lot of predefine string functions are available. Lets see some string function with example.

1. ToUpper() - ToUpper function converts string to upper case.
   

   string myName = "myName is Shreesh";
          myName = myName.ToUpper();
          Console.WriteLine(myName);

2. ToLower() - ToLower converts string to lower case.
   

    string myName = "myName is SHREESH";
   myName = myName.ToLower();
   Console.WriteLine(myName);

   
   

3. Trim()- Trim function removes extra spaces from the beginning and the ending of string.
   

   string myName = "     myName is SHREESH       ";
          myName = myName.Trim();
   Console.WriteLine(myName);

   
   

4. Contains()- Contains method return bool value, it checks whether specified string or character exist in string or not.
   

   string myName = "myName is SHREESH";
          bool  isContains = myName.Contains("SHREESH");
          Console.WriteLine(isContains);

   
   

5. ToCharArray()- Convert a string to array of character.
   

   string myName = "myName is SHREESH";
   char[] charArray = myName.ToCharArray();
   foreach(char c in charArray)
         {
       Console.WriteLine(c);
   }

   
   

6. Substring()- substring method returns substring of a string.
   

   string myName = "myName is SHREESH";
            myName =  myName.Substring(0, 6);
       Console.WriteLine(myName);

   
   

1. StartsWith()- Startswith method checks whether the first character of a string is same as specified character .It returns bool value.
   

   string myName = "myName is SHREESH";
              bool isContains = myName.StartsWith("my");
              Console.WriteLine(isContains);

   
   
   
2. Split()- Split function splits the string on the supplied value.It return the array of string.
   

   string myName = "myName-is-SHREESH";
     string[] breakMysentence = myName.Split('-');
     foreach (string data in breakMysentence)
          Console.WriteLine(data);
