Step 4: Building and Testing the Application

In this step, you will build and test your application. Visual Studio offers several methods to build and run a console application from the IDE, such as:

• Start Without Debugging ( CTRL + F5)

• Start ( F5)

Build, Run, and Debug the Application

To build and run the application

1. On the Debug menu, click Start Without Debugging or press CTRL + F5. This ensures that the console window remains open after the program has finished executing.

2. The application prints the following output to the console.

   [!NOTE] These values vary depending on the values you have in your workbook, session ID, and so on.

   The Credential is: System.Net.SystemNetworkCredential
   Total rows in range: 18
   Value in range is: 4245.955129
   

3. Press any key to close SampleApplication.exe.

File Not Found Exception

1. If the path to the workbook you provided is wrong, you will get a "file not found" exception, which is caught by the following code:

  
catch (SoapException e)
{
    Console.WriteLine("SOAP Exception Message: {0}", e.Message);
}

  
Catch e As SoapException
Console.WriteLine("SOAP Exception Message: {0}", e.Message)
End Try

2. The application prints the following SOAP exception output to the console:

  
SOAP Exception Message: The file you selected could not be found. Check the spelling of the file name and verify that the location is correct.

Index Out Of Range Exception

1. If you try to get a value from outside the range, you will get a System.IndexOutOfRangeException exception. The application prints the following output to the console:

  
The Credential is: System.Net.SystemNetworkCredential
The sessionID is : 64.28e58e90-b757-4658-b1c4-890ad68ef6cbRmqR4IINXfkMeOJRG8Iq0Y
27tVk=110.33d3R6fqv7tr2jPyYiPwRu|!@en-US|en-US|+0480#0000-10-00-05T02:00:00:0000
#+0000#0000-04-00-01T02:00:00:0000#-0060
Total rows in range: 18

2. Then you will get an unhandled exception that says:

  
An unhandled exception of type 'System.IndexOutOfRangeException' occurred in SampleApplication.exe
Additional information: Index was outside the bounds of the array.

3. You can handle the above unhandled exception by adding another catch block to catch the exception after the SOAP exception catch block as shown here:

  
catch (Exception e)
{
    Console.WriteLine("Exception Message: {0}", e.Message);
}

  
Catch e As Exception
Console.WriteLine("Exception Message: {0}", e.Message)
End Try

To run the application using F5

1. You can run your application by clicking Start on the Debug menu, or by pressing F5. To ensure that the console window remains open after the program has finished executing, you could add the following line of code at the end of your code (after the catch block):

  
Console.ReadLine();

  Console.ReadLine()

2. Press any key to close SampleApplication.exe.
