Generate C# Class from SQL Server Table

In SQL Server, you can generate a C# class from a table using a SQL query. This is useful when you want to create a strongly-typed class to interact with your database.

Method 1: Using sp_help

You can use the `sp_help` stored procedure to generate a C# class from a table.

DECLARE @TableName sysname = 'YourTableName'; DECLARE @CSharpClass nvarchar(max) = ''; SELECT @CSharpClass = @CSharpClass + ' public class ' @TableName + ' { ' + CHAR(13) + CHAR(10) + STUFF(( SELECT ' public ' CASE WHEN c.is_nullable = 1 THEN 'Nullable<' ELSE '' END + CASE c.user_type_id WHEN 167 THEN 'tring' WHEN 175 THEN 'byte[]' WHEN 231 THEN 'tring' WHEN 239 THEN 'tring' WHEN 241 THEN 'tring' ELSE 'int' END + CASE WHEN c.is_nullable = 1 THEN '>' ELSE '' END + ' + c.name + ' get; set; } ' + CHAR(13) + CHAR(10) FROM sys.columns c WHERE c.object_id = OBJECT_ID(@TableName) FOR XML PATH(''), TYPE).value('.', 'nvarchar(max)'), 1, 1, '') + ' }'; PRINT @CSharpClass; 

This will generate a C# class with properties matching the columns of the specified table.

Method 2: Using SQL Server Management Studio (SSMS)

You can use SSMS to generate a C# class from a table.

1. Open SSMS and connect to your database.
2. Right-click on the table you want to generate a class for and select "Script Table as" > "CREATE" > "To New Query Window".
3. In the generated script, remove the `CREATE TABLE` statement and modify the script to generate a C# class.

Example: Generating a C# Class for a Table

Let's say we have a table called `Employees` with the following columns:

Using the `sp_help` method, we can generate the following C# class:

public class Employees { public int EmployeeID { get; set; } public string FirstName { get; set; } public string LastName { get; set; } public string Email { get; set; } } 

Important Notes

When generating a C# class from a SQL Server table, keep in mind:

• The generated class will not include any business logic or validation.
• You may need to modify the generated class to fit your specific requirements.
• Make sure to test the generated class thoroughly before using it in your application.
