Algorithm

In C#, a string is a sequence of characters that represents text. It is one of the built-in data types in C# and is part of the .NET Framework. Here are some key points about C# strings:

 

Code Examples

#1 Example- Create string in C# Program

Code - C# Programming

using System;  
namespace CsharpString {  
  class Test {
    public static void Main(string [] args) {
      
      // create string
      string str1 = "C# Programming";
      string str2 = "DevsEnv";
      
      // print string
      Console.WriteLine(str1);
      Console.WriteLine(str2);

      Console.ReadLine();
    }
  } 
}

#2 Get the Length of a string in C# Program

Code - C# Programming

using System;  
namespace CsharpString {  
  class Test {
    public static void Main(string [] args) {

      // create string
      string str = "C# Programming";
      Console.WriteLine("string: " + str);
      
      // get length of str
      int length = str.Length;     
      Console.WriteLine("Length: "+ length);

      Console.ReadLine();
    }
  } 
}
Copy The Code & Try With Live Editor

Output

x
–
+
cmd
string: C# Programming
Length: 14

#3 Join two strings in C# Programming

Code - C# Programming

using System;  
namespace CsharpString {  
  class Test {
    public static void Main(string [] args) {

      // create string
      string str1 = "C# ";
      Console.WriteLine("string str1: " + str1);

      // create string
      string str2 = "Programming";
      Console.WriteLine("string str2: " + str2);
      
      // join two strings
      string joinedString = string.Concat(str1, str2);
      Console.WriteLine("Joined string: " + joinedString);

      Console.ReadLine();
    }
  } 
}
Copy The Code & Try With Live Editor

Output

x
–
+
cmd
string str1: C#
string str2: Programming
Joined string: C# Programming

#4 compare two strings in C# program

Code - C# Programming

using System;  
namespace CsharpString {  
  class Test {
    public static void Main(string [] args) {

      // create string
      string str1 = "C# Programming";
      string str2 = "C# Programming";
      string str3 = "DevsEnv";
      
      // compare str1 and str2
      Boolean result1 = str1.Equals(str2);
      Console.WriteLine("string str1 and str2 are equal: " + result1);

      //compare str1 and str3
      Boolean result2 = str1.Equals(str3);
      Console.WriteLine("string str1 and str3 are equal: " + result2);     

      Console.ReadLine();
    }
  } 
}
Copy The Code & Try With Live Editor

Output

x
–
+
cmd
string str1 and str2 are equal: True
string str1 and str3 are equal: False

#5 String interpolation in C# Programming

Code - C# Programming

using System;  
namespace CsharpString {  
  class Test {
    public static void Main(string [] args) {

      // create string
      string name = "DevsEnv";

      // string interpolation
      string message = $"Welcome to {name}";
      Console.WriteLine(message);

      Console.ReadLine();
    }
  } 
}
