My Store Procedure (Single Parameter) : 
 
ALTER procedure [dbo].[CountryInsert]
(
   @CountName varchar(50)
)
as
begin
   INSERT INTO [DevPayPension].[dbo].[Country]
              ([CountryName])
        VALUES
              (@CountName)
end
Entity Framework Code this is Single Parameter Pass: 
 
private void InsertData()
        {
           
                  using (var db = new EFPIMS())
                  {
                         db.CountryInsert(TextBox1.Text);
                  }
        }
 
Now How I can Pass Multiple parameter by Entity Framework ??
