C# String Utils

Documenting a few simple string utils I created for an app recently

Be sure to resolve usings as needed

public static string SingleSpace(string str)
{
	//replaces multiple spaces with one.
	RegexOptions options = RegexOptions.None;
	Regex regex = new Regex(@"[ ]{2,}", options);
	str = regex.Replace(str, @" ");
	return str;
}

public static string SlashFlip(string source, int direction)
{
	string returnVal = null;
	if (direction == 0) //back
	{
		returnVal = source.Replace(@"/", @"\");
	}
	else if (direction == 1) //forward
	{
		returnVal = source.Replace(@"\", @"/");
	}
	return returnVal;
}

public static string SlashTrim(string str)
{
	if (str.IndexOf(@"/") == 0 || str.IndexOf(@"\") == 0) //first char
	{
		str = str.Substring(1, str.Length - 1);
	}
	if (str.IndexOf(@"/") == str.Length || str.IndexOf(@"\") == str.Length) //last char
	{
		str = str.Substring(str.Length, 1);
	}
	return str;
}

public static string IdXml(string[] idArray)
{
	string returnXml = null;
	List ids = new List(); //list of id's for the XmlSerializer
	foreach (string id in idArray)
	{
		ids.Add(Convert.ToInt64(id));
	}
	//create Xml doc from list to pass id's into sproc as a single param
	XmlSerializer xs = new XmlSerializer(typeof(List));
	MemoryStream ms = new MemoryStream();
	xs.Serialize(ms, ids);
	returnXml = UTF8Encoding.UTF8.GetString(ms.ToArray());

	return returnXml;
}

public static string StripDomain(string userIdentityName)
{
	//remove domain name and back slash if present
	int i = userIdentityName.IndexOf(@"\");
	if (i > -1) userIdentityName = userIdentityName.Remove(0, i + 1);
	return userIdentityName;
}
