Represents the method that defines a set of criteria and determines whether the specified object meets those criteria.
Assembly: mscorlib (in mscorlib.dll)
- in T
The type of the object to compare.
This type parameter is contravariant. That is, you can use either the type you specified or any type that is less derived. For more information about covariance and contravariance, see Covariance and Contravariance in Generics.
The object to compare against the criteria defined within the method represented by this delegate.
Return ValueType: System.Boolean
true if obj meets the criteria defined within the method represented by this delegate; otherwise, false.
The following code example uses a delegate with the Array.Find(T) method to search an array of Point structures. The method the delegate represents, ProductGT10, returns true if the product of the X and Y fields is greater than 100,000. The Find(T) method calls the delegate for each element of the array, stopping at the first point that meets the test condition.
Visual Basic and C# users do not need to create the delegate explicitly, or to specify the type argument of the generic method. The compilers determine the necessary types from the method arguments you supply.
