I am having trouble removing a pipe character using Regex.Replace -
see the 2 NUnit tests below:

The first replace works fine and the second Replace does not work.
I've tried escaping the pipe character.

Can anyone get this to work?

Thanks

Glenn



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

namespace ScratchPad
{
    [TestFixture] public class ScratchPad
    {
        [Test] public void RegexReplace_o()
        {
            Regex r = new Regex("bob");
            Match m = r.Match("bob");
            Assert.AreEqual(true,m.Success);
            Assert.AreEqual("bb",Regex.Replace("bob","o",""));
        }
        [Test] public void RegexReplace_bar()
        {
            Regex r = new Regex("b|b");
            Match m = r.Match("b|b");
            Assert.AreEqual(true,m.Success);
            //Assert.AreEqual("bb",Regex.Replace("b|b","|",""));

        }
    }
}

Regex.Replace("b|b",@"\|","") // works for me

Thanks Jon - its obvious I need the string literal AND the escape - now
you show me.
