Example 1: c# string methods

string string1 = "Today is " + DateTime.Now.ToString("D") + ".";
Console.WriteLine(string1);

string string2 = "This is one sentence. " + "This is a second. ";
string2 += "This is a third sentence.";
Console.WriteLine(string2);

Example 2: C# string

string str1 = "Blue";
string str2 = "Duck";

//returns length of string
str1.Length;

//Make clone of string.
str2 = str1.Clone();

//checks whether specified character or string is exists or not
//in the string value.
str2.Contains(“hack”);

//checks whether specified character is
//the last character of string or not.
str2.EndsWith(“io”);

//compares two string and returns Boolean value true 
//as output if they are equal, false if not
str2.Equals(str1);

//Returns the index position of first occurrence of specified character.
str1.IndexOf(“:”);

//Converts String into lower case based on rules of the current culture.
str1.ToLower();

//Converts String into Upper case based on rules of the current culture.
str1.ToUpper();

//Insert the string or character in the string at the specified position.
str1.Insert(0, “Welcome”);

//Returns the index position of last occurrence of specified character.
str1.LastIndexOf(“T”);

//deletes all the characters from beginning to specified index position
str1.Remove(i);

//replaces the specified character with another
str1.Replace(‘a’, ‘e’);

//This method splits the string based on specified value.
string[] strArray = str1.Split(“/”);

//This method returns substring.
str1.Substring(startIndex , endIndex);

//It removes extra whitespaces from beginning and ending of string.
str1.Trim();

//returns HashValue of specified string.
str1.GetHashCode();

//This is not an exhaustive list.
