Is it possible to have a switch in a lambda expression? If not, why? Resharper displays it as an error.
C programming language is a machine-independent programming language that is mainly used to create many types of applications and operating systems such as Windows, and other complicated programs such as the Oracle database, Git, Python interpreter, and games and is considered a programming foundation in the process of ...
Compared to other languages—like Java, PHP, or C#—C is a relatively simple language to learn for anyone just starting to learn computer programming because of its limited number of keywords.
What is C? C is a general-purpose programming language created by Dennis Ritchie at the Bell Laboratories in 1972. It is a very popular language, despite being old. C is strongly associated with UNIX, as it was developed to write the UNIX operating system.
In the real sense it has no meaning or full form. It was developed by Dennis Ritchie and Ken Thompson at AT&T bell Lab. First, they used to call it as B language then later they made some improvement into it and renamed it as C and its superscript as C++ which was invented by Dr.
You can in a statement block lambda:
Action<int> action = x =>
{
switch(x)
{
case 0: Console.WriteLine("0"); break;
default: Console.WriteLine("Not 0"); break;
}
};
But you can't do it in a "single expression lambda", so this is invalid:
// This won't work
Expression<Func<int, int>> action = x =>
switch(x)
{
case 0: return 0;
default: return x + 1;
};
This means you can't use switch in an expression tree (at least as generated by the C# compiler; I believe .NET 4.0 at least has support for it in the libraries).
