        objConnection.Close();
        // Create a multidimensional jagged array
        string[][] JaggedArray = new string[objDataSet.Tables[0].Rows.Count][];
        int i = 0;
        foreach (DataRow rs in objDataSet.Tables[0].Rows)
        {
            JaggedArray[i] = new string[] { rs["Name"].ToString(), rs["Roll"].ToString(), rs["Class"].ToString() };
            i = i + 1;
        }
        // Return JSON data

        JavaScriptSerializer js = new JavaScriptSerializer();

Simple Java based SMPP Client Source Code to send SMS

This program needs the following java files to function.

1. SerialConnection.java (This file is used to connect to your COM port from your java program)

2. SerialConnectionException.java (This file is for handling serial connection exceptions in your Java program)

3. SerialParameters.java (This program is used to set your COM port properties for connecting to your com port from your java program)

4. Sender.java (This is the program that implements runnable and sends SMS using the serial connection)

5. SMSClient.java (This java class is the main class that can be instantiated in your own java program and called to send SMS. This program in turn will use all the above four files internally to send out your SMS).
