CurrentCultureIgnoreCase Property

StringComparer.CurrentCultureIgnoreCase Property


Gets a StringComparer object that performs case-insensitive string comparisons using the word comparison rules of the current culture.

Namespace:   System
Assembly:  mscorlib (in mscorlib.dll)

public static StringComparer CurrentCultureIgnoreCase { get; }

Property Value

Type: System.StringComparer

A new StringComparer object.

The current culture is the CultureInfo object associated with the current thread.

TheStringComparer returned by the CurrentCultureIgnoreCase property can be used when strings are linguistically relevant but their case is not. For example, if strings are displayed to the user but case is unimportant, culture-sensitive, case-insensitive string comparison should be used to order the string data.

The CurrentCultureIgnoreCase property actually returns an instance of an anonymous class derived from the StringComparer class.

Each call to the CurrentCultureIgnoreCase property get accessor returns a new StringComparer object, as the following code shows.

private void CompareCurrentCultureInsensitiveStringComparer()
   StringComparer stringComparer1, stringComparer2;
   stringComparer1 = StringComparer.CurrentCultureIgnoreCase;
   stringComparer2 = StringComparer.CurrentCultureIgnoreCase;
   // Displays false

To improve performance, you can store the StringComparer object in a local variable rather than retrieve the value of the CurrentCultureIgnoreCase property multiple times.
