StringComparer.Equals Method (String, String)

When overridden in a derived class, indicates whether two strings are equal.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)
public abstract bool Equals(
	string x,
	string y
)

Parameters

x
Type: System.String

A string to compare to y.

y
Type: System.String

A string to compare to x.

Return Value

Type: System.Boolean
true if x and y refer to the same object, or x and y are equal; otherwise, false.

Implements

IEqualityComparer<T>.Equals(T, T)

The StringComparer.Equals(String, String) method is more efficient than the StringComparer.Equals(Object, Object) method because the x and y parameters do not have to be unboxed to perform the comparison.
