Regarding Connection pooling

Question

Hi All,

Please guide me.

SqlConnection con = new SqlConnection();

con.ConnectionString = conn + "Connection Timeout=30;Connection Lifetime=0;Min Pool Size=0;Max Pool Size=1;Pooling=true;integrated security=true";

SqlCommand cmd = new SqlCommand("Storeprocedure", con);

cmd.CommandType = CommandType.StoredProcedure;

cmd.Parameters.AddWithValue("@Action", "Select");

con.Open();

SqlDataReader dr = cmd.ExecuteReader();

Grd1.DataSource = dr;

Grd1.DataBind();

con.Close();

In the above code i configure max pool size is 1 and every time i open and close the conection If i not closing the connection ,during reload binding grid again it wil reached out of the max pool size.

If i using open and close connection each time then the things becomes same that take more time consuming, what benefit of connection pooling.

Please guide me if i not closing the connection then how its beneficial and not reached out of the max pool size.

 

Thanks in advance
