SPListCollection ContainsList Extension Method

This is such a simple thing but something every SharePoint developer should have in their toolkit (well, actually, this is something Microsoft should put into the product). The SPFieldCollection has a nice method called ContainsField so you can check for the existence of a field (without throwing an exception if you get the spelling wrong). This is my version of the same method for SharePoint Lists.

 public static class SPListExtensions

{

public static bool ContainsList(this SPListCollection lists, string displayName)

{

try

{

return lists.Cast<SPList>().Any(list => string.Equals(list.Title, displayName, StringComparison.OrdinalIgnoreCase);

}

catch (Exception)

{

return false;

}

}

}
