    Remove the while(true) { and ending } and the code will only execute once.

    Do you know about the break statement?

    As Norm mentioned, there is not need for a while if you only need the code to execute once. If you need the code to execute at least once, the use do{} while()

    I need to use while loop as its the threads run method ,

    but in that loop i want a section of code to ecxecute once , or for a particular count..

    public Run()
    {

    while(true)
    {

    [ this section of code runs for 200 counts]

    [this scode runs only once]




    }

    If the section of code is inside the while loop, then use a boolean oneTime switch in an if statement
    Define the boolean variable as true outside the loop. The inside the loop:
    if (oneTime) {
       oneTime = false;  // flip the switch to prevent execution next loop around
       // do the one time stuff
    } // end if

    I don't see why it has to be inside the while loop - surely only the code that needs to run many times should be in the loop. One-time code should be before or after the loop, as appropriate.

    Also, if you need code executed 200 times, why not use a 'for..' loop that counts 200 iterations? A 'while(true)' loop is really only suitable for loops with an indefinite number of repeats (and not particularly good practice).
