Question

how to write below stored procedure in C#

i am creating class library file. i get a situation….not to give the scirpt file to clients…so i have to create SP in c# code. I desperately want to keep it in C# assembly
Let me know is this possible

IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[AdjustTax]') AND type in (N'P', N'PC'))

DROP PROCEDURE [dbo].[AdjustTax]

SET ANSI_NULLS ON

Why would you write it in C# in the first place?

If you want to manage DB schema use Visual Studio Database project.

If you desperately want to keep it in C# assembly, create a separate .sql file, embed it as a resource and load it in C# as a string.

In file properties change Build Action to Embedded Resource and use the following code to load it

using (Stream stream = Assembly.GetExecutingAssembly()
                               .GetManifestResourceStream("Your assembly namespace" + "file.sql"))
using (StreamReader reader = new StreamReader(stream))
{
    string result = reader.ReadToEnd();
}
