Exception thrown: 'System.Data.SqlServerCe.SqlCeException' in System.Data.SqlServerCe.dll

Lakshman Balasubramanian 21

Hello All,

I facing an issue with the following error. When I build the project it successfully builds but then when I execute it I am not getting the output window. When checked, I noticed that I am facing an issue when I run. The following exceptions are thrown. It would be great if you could suggest me some fixes for these issues.

Issue:

User's image

In the output console, the following messages are shown:

Exception thrown: 'System.Data.SqlServerCe.SqlCeException' in System.Data.SqlServerCe.dll

Exception thrown: 'System.ArgumentNullException' in EntityFramework.dll

An exception of type 'System.ArgumentNullException' occurred in EntityFramework.dll but was not handled in user code

Value cannot be null.

Much appreciated for your time and work, TIA.

Hi @Lakshman Balasubramanian , Welcome to Microsoft Q&A,

Maybe you can show the code you used (removing private information). From the error message, it seems that the value you used is empty. And you are not using error handling in your code.

You need to make some changes here, such as adding error handling. To get the reason behind an exception, you need to check the exception's properties: Errors

try { //Your code here } catch (SqlCeException e) { foreach (SqlCeError error in e.Errors) { //Error handling, etc. MessageBox.Show(error.Message); } }
