SQL Server & .net support calling a stored procedure with param's values wihout providing param's names?

I want to call a command.ExecuteReader() of type Stored Procedure, however I do not want the parameter names that I pass to be identical to the ones in the SP. Below is a sample of what I’m trying to do

SP:

ALTER PROCEDURE SPName
@Id nvarchar(50)
AS
BEGIN
    SET NOCOUNT ON;
SELECT * FROM TableName
WHERE ColumnName = @Id 
END
GO

Code:

using (SqlCommand command = new SqlCommand(spName, connection) { CommandType = CommandType.StoredProcedure })
{
    command.parameters.Add(new SqlParameter(*paramaeter name*, sqlDbType.nvarchar){ Value = "SomeValue"};
}

Simple fact – you ultimately have to use the correct parameter name when calling a stored procedure because SQL server binds parameters by name (even when you use EXEC to call an SP without using named parameters, the parser binds them by name from left to right).

So if you want to use a different name you will need to introduce an intermediate layer between your SqlCommand and the target SP.

But if you just want to not care about the name and have it automatically discovered – then you can use the technique mentioned by Conrad Frix in his accepted answer on SQL Server & .net support calling a stored procedure with param's values wihout providing param's names? – which is why I’ve marked as a duplicate, because it is ultimately what you want to do, even if the reasons are different.
