Example 2: Using the AddOutputParameter method to add an output parameter with a given name and type.csharp
Example 3: Using the AddParameterWithValue method to add a parameter with a given name and value, and automatically determine the parameter type.csharp var command = new SqlCommand(); SqlParameterHelper.AddParameterWithValue(command, "@LastName", "Doe"); ``` These examples demonstrate how to use the various methods of the SqlParameterHelper class to create SQL parameters for a command object. They show how to create input and output parameters of different types, and how to set their values. The mojoPortal.Data package library provides these helper classes to make it easier to work with SQL parameters in .NET applications.
