  Why don't you store the input in a file and then try to run that file. I haven't worked with C#, but you can give it a try.

  Yes, the easiest thing to do will be to store that string in a file, then read that file using CS compiler..

  There must be some way, in PHP and Javascript there is a function named eval that we can use to execute a string as a code

  If I understand this correctly, then the technique is quiet similar to online compilers.
  If you are trying to implement this, then be sure to check all boundary conditions, like time limit to terminate the program by force, checking for non-malicious code and etc.

  Its fine that we store that code in a seperate file but how to execute that code in the same program?

  I want to execute the inputted code..if that code has errors then the compiler should gives error mes as we normally get error mes when we compile a code.

  Are you looking for code like below in Java
  
  Program to be compiled & executed
  
  

  package myjava;
  public class HelloWorld extends java.lang.Object{
      private HelloWorld(){
      }
  
      /**
       * [USER=14158]param[/USER] args
       * 
       */
      public static void main(String[] args) {
          System.out.println("Hello World executed !!");
      }
  
  }
  

  Program that will execute above program
  
  

  package myjava;
  
  import java.io.BufferedReader;
  
  import java.io.InputStreamReader;
  
  public class CompileOneProgramFromAnother {
  
      /**
  
      * [USER=14158]param[/USER] args
  
      */
  
      public static void main(String[] args) {
  
          try {
  
              Runtime rt = Runtime.getRuntime();
  
              Process compileProcess = rt
  
                      .execute("javac D:\\MyJavaWorkspace\\Test\\src\\myjava\\HelloWorld.java");
  
              System.out.println("CompileOneProgramFromAnother | Program is compiled successfully !!");
  
              Process runProcess = rt
  
                      .execute("java -classpath D:\\MyJavaWorkspace\\Test\\src myjava.HelloWorld");
  
              InputStreamReader isr = new InputStreamReader(
  
                      runProcess.getInputStream());
  
              BufferedReader br = new BufferedReader(isr);
  
              String line = null;
  
              System.out.println("********************OUTPUT of HELLO WORLD.JAVA ***************\n");
  
              while ((line = br.readLine()) != null)
  
                  System.out.println(line);
  
              System.out.println("\n********************END OUTPUT of HELLO WORLD.JAVA ***************");
  
              int exitVal = runProcess.waitFor();
  
              System.out.println("CompileOneProgramFromAnother | Process exitValue: " + exitVal);
  
          } catch (Exception e) {
  
              e.printStackTrace();
  
          }
  
      }
  
  }
  
  

  Output:
  
  CompileOneProgramFromAnother | Program is compiled successfully !!
  ********************OUTPUT of HELLO WORLD.JAVA ***************
  
  Hello World executed !!
  
  ********************END OUTPUT of HELLO WORLD.JAVA ***************
  CompileOneProgramFromAnother | Process exitValue: 0

  Well it smells like injections to me. Are you trying to patch the script or make a vulnerable code?
  
  Or if you want to run an external code in the same program, a good option is:
  
  Learn about CSRF. we will do something like that
  Now copy the input code on clipboard.
  Create a CSRF link for an online compiler and the code to be input to be taken from the clipboard. Run the code there. then copy the output on clipboard and use it accordingly where required.
  
  Another way also suggested by others is to accept the input in a text file. Now create a batch program which runs the code and stores output on clipboard. Then use the output accordingly.

  Create a batch file. That will help
