One example is the argument to the Task.Run(Action) method to pass the code that should be executed in the background. You can also use lambda expressions when you write LINQ in C#, as the following example shows:C# Copy Run int[] numbers = { 2, 3, 4, 5 }; var squaredNumbers ...

for example in LINQ to SQL, the parameter type is an expression tree typeExpression<Func<TSource,TResult>>. In both cases, you can use the same lambda expression to specify the parameter value. That makes the twoSelectcalls to look similar although in fact the type of objects created from...
Language Integrated Query (LINQ) is a great way to access data from many different sources. LINQ provides a single querying model that can operate against different data domains individually or all together in a single query. LINQ brings the ability to query data to .NET languages, and some ...
