[C#]

The following C# Code shows how to query for the XMin, YMin, XMax and YMax coordinates.

private void QueryCoordinates()
{
    IEnvelope envelope = new EnvelopeClass();
    envelope.PutCoords(100, 100, 200, 200);
    double minX;
    double minY;
    double maxX;
    double maxY;
    envelope.QueryCoords(out minX, out minY, out maxX, out maxY);
    String report = " \n" +
                     "LowerLeft  X =  " + minX + "\n" +
                     "LowerLeft  Y =  " + minY + "\n\n" +
                     "LowerRight X =  " + maxX + "\n" +
                     "LowerRight Y =  " + minY + "\n\n" +
                     "UpperLeft  X =  " + minX + "\n" +
                     "UpperLeft  Y =  " + maxY + "\n\n" +
                     "UpperRight X =  " + maxY + "\n" +
                     "UpperRight Y =  " + maxY;
    System.Windows.Forms.MessageBox.Show(report);

}
