need help to fix C# code problem

[zleug]

Hi All.

In Data layer I have EmployeeFactory class with method

public static int SaveEmployee(EmployeeDt emp)
{
...
}

And I'm using this method in the Business layer in EmployeeAdapter class

public int SaveData(EmployeeDt emp)
{
return EmployeeFactory.SaveEmployee(emp);
}

In the UI layer in the click Save button event I specify EmployeeAdapter

private void SaveButton_Click(object sender, EventArgs e)
{

...

EmployeeAdapter.SaveData(emp);

...
}


and line code EmployeeAdapter.SaveData(emp) indicate error:
An object reference is required for the non-static field, method, or property 'EmployeeAdapter.SaveData(EmployeeDt)'.

How to fix this problem?

Thanks.
