'SqlConnection' is not declared error for aspx net - asp.net

Question

I am fairly new to this Aspx.Net. I am trying to connect to a remote SQL Server and below is the connection string I am trying on IIS server.
SQL Server version is 2012
MySqlConnection connection = new MySqlConnection("Database=DB;Server=server.name;Uid=user.name;Pwd=pass");
connection.Open();
MySqlCommand command = connection.CreateCommand();
command.CommandText = "select * from dbo.TableName";
MySqlDataReader reader = command.ExecuteReader();
while (reader.Read())
{
//reader.GetString(0)
//reader["column_name"].ToString()
}
reader.Close();
Below is the error:
Server Error in '/' Application.
Compilation Error
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.
Compiler Error Message: BC30451: Name 'SqlConnection' is not declared.
Appreciate any help, please keep in mind this is my first tries out on aspx. Yes, I tried searching online but can't seem to find a resolution.

Well, if you want to use SQL Server in C#, try follow below technique:
SqlConnection sqlConn = new SqlConnection("Server=server.name;Database=DB;User Id=userid;Password=yourpass;");
SqlCommand cmd = new SqlCommand("select * from dbo.TableName", sqlConn);
sqlConn.Open();
SqlDataReader reader = cmd.ExecuteReader();
while (reader.Read())
{
//reader.GetString(0)
//reader["column_name"].ToString()
}
reader.Close();
sqlConn.Close();
