DbException

DbException is a class in the .NET Framework that represents errors generated by the ADO.NET data provider for a specific data source. It is part of the System.Data.Common namespace and serves as a base class for more specific exceptions related to database operations. DbException is designed to handle a wide range of database-related errors, including connection issues, command execution failures, and data retrieval problems.

When a database operation fails, the ADO.NET data provider throws a DbException or one of its derived classes, such as SqlException for SQL Server or OracleException for Oracle databases. These exceptions provide detailed information about the error, including an error code, a message describing the problem, and a stack trace that can help developers diagnose and fix the issue.

DbException is an abstract class, meaning it cannot be instantiated directly. Instead, developers should catch instances of its derived classes in their code to handle database-related errors appropriately. By catching and handling these exceptions, developers can implement error recovery strategies, log error details, and provide meaningful feedback to users.

In summary, DbException is a crucial component of the .NET Framework's ADO.NET data access technology. It helps developers handle and manage database-related errors effectively, ensuring more robust and reliable data-driven applications.
