Operator operator ==

operator ==(NSError, NSError)

Tests whether the underlying pointers for two NSError objects are the same.

Declaration

public static bool operator ==(NSError lhs, NSError rhs)

Parameters

Type	Name	Description
NSError	lhs	The NSError to compare with rhs.
NSError	rhs	The NSError to compare with lhs.

Returns

Type	Description
bool	Returns true if the underlying pointers of lhs and rhs are the same. Returns false otherwise.

Remarks

This only tests whether two NSErrors point to the same object in memory. Two different NSErrors could still be considered equal. See Equals(NSError).

operator ==(NSError?, NSError?)

Tests for equality.

Declaration

public static bool operator ==(NSError? lhs, NSError? rhs)

Parameters

Type	Name	Description
NSError?	lhs	The nullable NSError to compare with rhs.
NSError?	rhs	The nullable NSError to compare with lhs.

Returns

Type	Description
bool	Returns true if any of these conditions are met: - lhs and rhs are both not null and their underlying pointers are equal. - lhs is null and rhs's underlying pointer is null. - rhs is null and lhs's underlying pointer is null. - Both lhs and rhs are null. Returns false otherwise.

Remarks

This equality operator allows you to compare null with an NSError to determine whether its underlying pointer is null. This allows for a more natural comparison with the Objective-C object:

void TestForNull(NSError error)
{
    // True if the native NSError object is null.
    if (error == null)
    {
        // Do something with the error
    }
}
