What is wrong with this auto-generated t-sql query?

Question

I'm having trouble executing a stored proc...

I've got C# code that tries to call the stored proc. It looks somewhat like this:

DataTable myDataTable = new DataTable();
using (SqlConnection connection = new SqlConnection(myConnectionString))
{
    SqlCommand selectCommand = new SqlCommand("MyStoredProc", connection);
    selectCommand.Parameters.Add(new SqlParameter("@myGuid", myGuid));
    SqlDataAdapter da = new SqlDataAdapter(selectCommand);
    da.Fill(myDataTable);
}

When I execute it, I get an error that reads "Incorrect syntax near 'MyStoredProc'".

If I run SqlProfiler, I see that it's attempting to run my stored proc like this:

exec sp_executesql 
N'MyStoredProc',
N'@myGuid uniqueidentifier',
@myGuid='FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF'

And sure enough, if I try to do the same thing, I get the same error. So my questions are:

1. What's wrong with the generated query?
2. Why is C# generating an invalid query? Did I do something wrong in my C# code?

EDIT: Agent_9191 nailed it...I was foolishly leaving out the statement to set the selectCommand type to StoredProcedure. The new generated query is:

exec MyStoredProc @myGuid='FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF'

and this (of course) works fine.

make sure to set your selectCommand.CommandType = CommandType.StoredProcedure.
