referencing a dll

[abhijit]

i am able to use this in an exe, or even compile it as a dll, but I am not able to use it in other projects.
any clues?

regards,

namespace StrClass
{
	/*
	 * My First Class with C#.
	 * I could not find a function to reverse a string in c# 
	 * strReverse is only present in VB.NET so I wrote one myself.
	 * -Abhijit
	 */
	public class StrReverse
	{
		public string strReverse(string sInput) 
		{
			//Function To Reverse a string
			char[] c;
			c = sInput.ToCharArray();
			string revstring = " ";
			for(int i = c.Length;i != 0;i--)
			{
				revstring =  revstring  + c[i-1].ToString();
			}
			return revstring;
		}
	}
}
/*
namespace testApp
{
	class mainapp
	{
		public static void Main()
		{
			StrClass.StrReverse a = new StrClass.StrReverse();
			string zzz = a.strReverse("Cool");
			Console.WriteLine("{0}",zzz);
		}
	}
}

I think its do with the names that I am using. I used the following and it has worked correctly. Any comments please?

using System;
namespace bbb
{
	/*
	 * My First Class with C#.
	 * I could not find a function to reverse a string in c# 
	 * strReverse is only present in VB.NET so I wrote one myself.
	 * -Abhijit
	 */
	public class zzz
	{
		public string abc(string sInput) 
		{
			//Function To Reverse a string
			char[] c;
			c = sInput.ToCharArray();
			string revstring = " ";
			for(int i = c.Length;i != 0;i--)
			{
				revstring =  revstring  + c[i-1].ToString();
			}
			return revstring;
		}
	}
}
/*
namespace testApp
{
	class mainapp
	{
		public static void Main()
		{
			StrClass.StrReverse a = new StrClass.StrReverse();
			string zzz = a.strReverse("Cool");
			Console.WriteLine("{0}",zzz);
		}
	}
}
