When creating your own exceptions, end the class name of the user-defined exception with the word "Exception", and implement the three common constructors, as shown in the following example. The example defines a new exception class named EmployeeListNotFoundException. The class is derived from...
Thedepartmenttable in the next example has a column whose type is the object typelocationdefined in the previous example. The example defines constraints on scalar attributes of thelocationobjects that appear in thedept_loccolumn of the table. CREATE TABLE department (deptno CHAR(5) PRIMARY KEY,d...
In this article, you will learn how to create user-defined exceptions that are inherited from the baseExceptionclass with localized exception messages using satellite assemblies.

If user name and/or password are invalid, then raise the appropriate exception. This example allows only users defined in the users config properties object. Check if the passed-in user has been defined for the system. We expect to find and match the property corresponding to the credentials ...
A conversion between two user-defined types can be defined in either of the two types. The following example demonstrates how to define an implicit and explicit conversion: C# Copy using System; public readonly struct Digit { private readonly byte digit; public Digit(byte digit) { if (...
An exception to this principle that user variables cannot be used to provide identifiers, is when you are constructing a string for use as a prepared statement to execute later. In this case, user variables can be used to provide any part of the statement. The following example illustrates ho...
