LINQ - Usage of Convert All Method

In this article we are going to see a usage of convert all method. If we want to convert the data type of values present in the collection then we can do it through ConvertAll.

/* Convert All method */

   var results = new List<object>() { 1, 0, 1, 1, 0, "true" };

   List<bool> boolresults = results.ConvertAll(x => Convert.ToBoolean(x));

   foreach (bool res in boolresults)

             Console.WriteLine(res);

In this example we have a list of values which are in object type , so we are converting all to the boolean type. Now the value 1 and "true" are cast as Bool True. and 0 as False.

Output:

True

False

True

True

False

True

I hope from this you can understand the usage of ConvertAll() method.
