This paper analyzes the use of predicate and func generic Delegate in C # By example, and shares it for everyone's reference. Specific as follows:Let's take a look at the following example:static void Main (string[] args) { list L = new list (); L.
Using system; namespace funcdemo {internal class program {Private Static void main () {// similar to the delegate function func func = tsetfunction; console. writeline ("first method:"); console. writeline (func (New inputargs ("zhangqs008", "123456
Func is a delegate, which is added in 3.5, 2.0 inside we use the delegate is located under the System.core namespace, using a delegate can improve efficiency, such as in reflection can compensate for the loss of performance of the Delegate,func.The
Static VoidMain (){Predicate Int> P = s => {ReturnS>1;};//This definition indicates that the parameter used by the function acting as a predicate must be a single value (its type must be the same as the data type in the array or list to be processed)
These two are system-built delegation,
With these two ready-made delegates, we can save the steps for customizing simple delegates.Action only parameters do not return values.Func both parameters and return valuesT indicates the parameter type of
predicate Generic delegate: Represents a method that defines a set of conditions and determines whether the specified object conforms to those conditions. This delegate is used by several methods of the Array and list classes to search for elements
The limbda expression is referenced in C #3.0. The limbda expression is actually a method, but this method is an anonymous method (that is, a method without a name)
CodeFragment: func T = (int x, string B) => (X. tostring () + B); equal
