Within C# is it possible to create a new function on the fly to define a variable?
I know that
string getResult() {
if (a)
return "a";
return "b";
}
String result = getResult();
is possible, but I'm looking for something like
String result = new string getResult() {
if (a)
return "a";
return "b";
}
Is this possible? If so, would someone demonstrate?
EDIT It is possible
Edit: Final - Solution
This is the end result of what I barbarically hacked together
Func<string> getResult = () =>
{
switch (SC.Status)
{
case ServiceControllerStatus.Running:
return "Running";
case ServiceControllerStatus.Stopped:
return "Stopped";
case ServiceControllerStatus.Paused:
return "Paused";
case ServiceControllerStatus.StopPending:
return "Stopping";
case ServiceControllerStatus.StartPending:
return "Starting";
default:
return "Status Changing";
}
};
TrayIcon.Text = "Service Status - " + getResult();
One way to define such a function:
Func<bool, string> getResult = ( a ) => {
if (a)
return "a";
return "b";
}
You can then invoke: string foo = getResult( true );
. As a delegate, it can be stored/passed and invoked when needed.
Example:
string Foo( Func<bool, string> resultGetter ){
return resultGetter( false );
}
You can also close around variables within scope:
bool a = true;
Func<string> getResult = () => {
if (a)
return "a";
return "b";
}
string result = getResult();
You want to use the inline if statement.
string result = a ? "a" : "b";
