[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Determines whether the specified objects are equal.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- x
- Type: System.Object
The first object to compare.
- y
- Type: System.Object
The second object to compare.
| Exception | Condition |
|---|---|
| ArgumentException | x and y are of different types and neither one can handle comparisons with the other. |
Implement this method to provide a customized equality comparison for objects.
Notes to ImplementersThe Equals method is reflexive, symmetric, and transitive. That is, it returns true if used to compare an object with itself; true for two objects x and y if it is true for y and x; and true for two objects x and z if it is true for x and y and also true for y and z.
Implementations are required to ensure that if the Equals method returns true for two objects x and y, then the value returned by the GetHashCode method for x must equal the value returned for y.
