Calling C# selenium methods between classes

I have two classes.
1) Environment.cs - where I set up all sorts of general methods.
2) AboutPage.cs - actual test case.

I have AboutPage.cs pull methods from Environment.cs In this case it is page loading time. When I try to build it, it gives me an error: : An object reference is required for the non-static field, method, or property Environment.cs

I am new to C#. Does anyone know how to solve this problem? I am attaching source code for both methods below.
Thanks!





using System;
using System.Text;
using System.Text.RegularExpressions;
using System.Threading;
using NUnit.Framework;
using Selenium;

namespace OldVersion
{
[TestFixture]
public class Environment
{
private ISelenium selenium;
private StringBuilder verificationErrors;

[Test]
public static void MeWaitForPageToLoad()
{
selenium.WaitForPageToLoad("30000");
}
}
}






using System;
using System.Text;
using System.Text.RegularExpressions;
using System.Threading;
using NUnit.Framework;
using Selenium;

namespace OldVersion
{
[TestFixture]
public class AboutPage
{
private ISelenium selenium;
private StringBuilder verificationErrors;

[SetUp]
public void SetupTest()
{
selenium = new DefaultSelenium("localhost", 4444, "*iexplore", "http://*******.com/");
selenium.Start();
verificationErrors = new StringBuilder();
}

[TearDown]
public void TeardownTest()
{
try
{
selenium.Stop();
}
catch (Exception)
{
// Ignore errors if unable to close the browser
}
Assert.AreEqual("", verificationErrors.ToString());
}

[Test]
public void FunctionsAboutPage()
{
selenium.Open("/en/default.aspx");
Environment.MeWaitForPageToLoad();
selenium.Click("ctl00_TopMenu1_About");
Environment.MeWaitForPageToLoad();
Assert.IsTrue(selenium.IsTextPresent("Software Development"));
Assert.IsTrue(selenium.IsTextPresent("Alliances"));
Assert.IsTrue(selenium.IsElementPresent("//img[@alt='Climate Savers']"));
Assert.IsTrue(selenium.IsElementPresent("//img[@alt='Novell']"));
Assert.IsTrue(selenium.IsElementPresent("//img[@alt='LANDesk']"));
Assert.IsTrue(selenium.IsElementPresent("//img[@alt='Microsoft']"));
Assert.IsFalse(selenium.IsTextPresent("asdfwc"));
}
}
}

roy,

since it is public you are getting that problem. Use static class to make use of methods without creating objects from other classes.

use "public static class Environment" instead public class Environment
