Hi,

 

Regarding Grouping Your Messages

 

Assuming that the numbers you are planning on sending to are housed in a database, you should be able to get a collection of the 1000 numbers that you are planning on sending to and simply grabbing 100 number sections at a time though LINQ :

 

// Grab your List of numbers to send to

var recipients = ExampleContext.Users.Select(x => x.MobileNumber).ToList();

// Store the batches to process

var batchesToProcess = numbers.Count() / 100;

// Loop through your numbers (100 at a time)

for(int i = 0; i <= batchesToProcess; i++)

{

// Output your first batch (of 100 numbers)

var batch = numbers.Skip(i * 100).Take(100);

// Send to each in this batch

foreach(var number in batch)

{

// Code to send SMS message here

}

// Consider placing a delay between each batch here

Thread.Sleep(6000);

}

 

Hope it helps...
