Yield keyword in C Sharp

  
C Sharp and yield keyword

Hi,



One of the cool and yet most unknown feature of the C# is the yield keyword. The yield keyword is used in an iterator block to provide a value to the enumerator object or to signal the end of the iteration. When used the expression is evaluated and returned as a value to the enumerator object. Note the expression has to be implicitebly convertible to yield type of the iterator. Here is an example



public static IEnumerable GetIntCollectionFromString(string SomeString){ string[] val = SomeString.Split(' '); int intToAdd; foreach (string token in val) { if (int.TryParse(token, out intVal)) { yield return intVal; } else { yield break; } }}

Here since we are using the yield keyword the function will return the collection of intVal instead of the value of intVal. The statement will only return when the iteration of the loop is complete.



There are some limitation with the yield keywords.

How to remove a Session variable?

  
using HttpSessionState.Remove(); (More...)

Is it possible to set SessionState to readonly mode? Readonly mode means, we can only read data from session but we can not write any data in session variable?

  
Yes, it is possible.
EnableSessionState property has a value "Readonly" which actually makes the session state read only.

Thanks. (More...)

Whether VBscript or Javascript which is better?

  
Javascript. Since it is platform independent. (More...)

I was trying to use an "out int" parameter in one of my functions. How should I declare the variable that I am passing to it?

  
You should declare the variable as an int, but when you pass it in you must specify it as 'out', like the following: int i; foo(out i); where foo is declared as follows: [return-type] foo(out int o) { } (More...)
