        fromInclusive : int *

        body : Action<int> -> IAsyncResult

IAsyncResult
An IAsyncResult that represents the asynchronous operation, which could still be pending.

In .NET Framework 4.0 and above you can use also the ForAsync(Int32, Int32, ActionInt32) method.

To get the result or the exception that occurred during the operation you have to call the EndFor method.

If fromInclusive is greater than or equal to toExclusive, then the operation completes synchronously without performing any iterations.

Note

This method adjusts the degree of parallelization automatically and does not support cancellation or reporting progress. Use the BeginForT(T, Int32, Int32, AsyncConfig, ActionInt32) overload to adjust parallelization, set up cancellation, report progress; or the ForAsyncT(T, Int32, Int32, TaskConfig, ActionInt32) method if you target .NET Framework 4.0 or later.
