How to check if string value exists in a list using C#

In this post, I will explain with an example, how to check string value exist in a list using C# and it will be quicker than LINQ.

here, string comparison specifies the culture, case and sort rules to be used by string methods.

	/// <summary>
	/// Method to check if a string value exists in a list. Will be quicker than Linq.
	/// </summary>
	/// <param name="list">The list of strings.</param>
	/// <param name="match">The item to match.</param>
	/// <param name="comparisonType">The type of comparison to perform.</param>
	/// <returns>True/false indication of whether the item exists in the list.</returns>
	private bool ListMatch(IList<string> list, string match, StringComparison comparisonType)
	{
	bool result = false;
	if ((list != null) && (list.Count > 0))
	{
	foreach (string item in list)
	{
	int compare = string.Compare(item, match, comparisonType);
	if (compare == 0)
	{
	result = true;
	}
	}
	}
	return result;
	}
