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

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.
