Enterprise library Error

[devendran]

Hi there,

I am new to Enterprise Library. When I am trying to pull data form database by using the method Execute Dataset I am getting the following error message.

"Invalid section name. The section 'PolicyConfig' does not exist in the requested configuration file 'D:\SanDiskIntegration\SanDiskIntegration\SanDisk. Client\bin\debug\SanDisk.Client.exe.Config' or the file 'C:\winnt\microsoft.net\framework\V1.1.4322\Config \Machine.Config'. Make sure that the 'enterpriselibrary.configurationSections' configuration section exists in one of the files and that the section 'PolicyConfig' is defined. "

As of my knowledge the reference Config is added and the file configmanager.cs is also added.

The peace of the coding is

private void button1_Click(object sender, System.EventArgs e)
{
try
{
string str = Convert.ToString(DataAcessHelper.ExecuteDataset("G etProductName"));
TB1.Text = str;
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}


Can anybody help me out of this error.
