StringComparer.Compare Method

Definition

Compares two objects or strings and returns an indication of their relative sort order.

Overloads

Compare(Object, Object)

When overridden in a derived class, compares two objects and returns an indication of their relative sort order.

Compare(String, String)

When overridden in a derived class, compares two strings and returns an indication of their relative sort order.

StringComparer.cs
Source:

When overridden in a derived class, compares two objects and returns an indication of their relative sort order.

public:
 virtual int Compare(System::Object ^ x, System::Object ^ y);
public int Compare (object? x, object? y);
public int Compare (object x, object y);
abstract member Compare : obj * obj -> int
override this.Compare : obj * obj -> int
Public Function Compare (x As Object, y As Object) As Integer

Parameters

x
Object

An object to compare to y.

y
Object

An object to compare to x.

Returns

A signed integer that indicates the relative values of x and y, as shown in the following table.

Value Meaning
Less than zero x precedes y in the sort order, or x is null and y is not null.
Zero x is equal to y, or x and y are both null.
Greater than zero x follows y in the sort order, or y is null and x is not null.

Implements

Exceptions

Neither x nor y is a String object, and neither x nor y implements the IComparable interface.

Remarks

The StringComparer.Compare(String, String) method is slightly more efficient than the StringComparer.Compare(Object, Object) method because no conversion of the x and y arguments is needed to perform the comparison.
