What Is The Method To Invoke A Stored Procedure Using Entity Framework 6 (code-first) In C#?

To call a stored procedure in Entity Framework 6 using Code-First approach, you can follow these steps:

Step 1: Create a Model class for the stored procedure result

public class MyStoredProcedureResult
    // Properties representing the result columns of the stored procedure
    public int Id { get; set; }
    public string Name { get; set; }

Step 2: Define the Stored Procedure in the DbContext

public DbSet<MyStoredProcedureResult> MyStoredProcedureResults { get; set; }

protected override void OnModelCreating(DbModelBuilder modelBuilder)
    // Define stored procedure mapping
        .MapToStoredProcedures(s =>
            s.Update(u => u.HasName("MyStoredProcedureName"));
            s.Insert(i => i.HasName("MyStoredProcedureName"));
            s.Delete(d => d.HasName("MyStoredProcedureName"));

Step 3: Call the Stored Procedure

using (var context = new YourDbContext())
    var results = context.MyStoredProcedureResults.SqlQuery("EXEC MyStoredProcedureName").ToList();
    foreach (var result in results)
        // Access properties of the stored procedure result
        Console.WriteLine($"Id: {result.Id}, Name: {result.Name}");

Note: In Step 2, make sure to replace "MyStoredProcedureName" with the actual name of your stored procedure.

That’s it! You can now call the stored procedure and access the result using Entity Framework 6 Code-First.
