type or namespace 'ADO' problem
Hi,
Here is how the codes look like:
////Program to create table
namespace database1
{
using System;
using System.Data.ADO;
public class Class1
{
public Class1()
{
//
// TODO: Add Constructor Logic here
//
}
public static int Main(string[] args)
{
try
{
ADOConnection s = new ADOConnection("Data Source=mymdb");
s.Open();
Console.WriteLine("Connection established");
//Create the table
Console.Write("Do you want to create a table?(y/n) ");
string ch = Console.ReadLine();
if (ch == "y")
{
ADOCommand CreateTable = new ADOCommand("Create Table Table1(vno integer,name char(20))", s);
CreateTable.ExecuteNonQuery();
Console.WriteLine("ADOCommand executed / Table created");
}
//Insert values into the table
Console.Write("Do you want to insert some values in a table?(y/n) ");
ch = Console.ReadLine();
if (ch == "y")
{
ADOCommand InsTable = new
ADOCommand("insert into Table1 values(1, 'hi')", s);
InsTable.ExecuteNonQuery();
Console.WriteLine("Values inserted");
}
//Delete the whole table
Console.Write("Do you want to delete all records present in the table?(y/n) ");
ch = Console.ReadLine();
if (ch == "y")
{
ADOCommand DeleteTable = new ADOCommand("Delete from Table1", s);
DeleteTable.ExecuteNonQuery();
Console.WriteLine("All records deleted");
}
//View all records
Console.Write("Do you want to view all records present in the table (y/n)? ");
ch = Console.ReadLine();
if (ch == "y")
{
ADOCommand AllRecs = new ADOCommand("select * from Table1", s);
//AllRecs.ExecuteNonQuery();
ADODataReader r;
AllRecs.Execute(out r);
while (r.Read())
{
for (int i = 0; i < r.FieldCount; i++)
{
Console.Write(r.GetValue(i) + " ");
}
Console.WriteLine();
}
Console.WriteLine("All Records Displayed");
r.Close();
}
s.Close();
Console.ReadLine();
}
catch (System.Exception e)
{
Console.WriteLine(e.ToString());
Console.ReadLine();
}
return 0;
} // Main End
} // Class Ends
}// namespace ends
//End of program
I'm getting the following error:
The type or namespace name 'ADO' does not exist in the namespace 'System.Data' (are you missing an assembly reference?)C:\Documents and Settings\rm\Desktop\Program\test1\Program.cs
Line 4
Column 23
Project database1
Pls help me to sort this out
Thx in advance
