How does the c# compiler concat strings

Question

Does C# optimize the concatenation of string literals?

string foo = "bar1" + "bar2" + "bar3";

Does the c# compiler internally apply the string.Concat method ?

Then it would be better to use the + operator for the readability sake.

yes its a dupe, See [this](http://stackoverflow.com/a/288913/368070) answer on the same post. — gideon, Jan 14 '12 at 19:33

With literals, this is equivalent to:

string foo = "bar1bar2bar3";

No concatenation is performed- they are combined at compile time into a constant.

I think he meant in a case where you'd say `string foo = "bar: " + bar + " (bar bar)";` where `bar` is unknown at compile time. – Tim Jan 14 '12 at 19:29

Possibly, but he didn't write the question that way. – Chris Shain Jan 14 '12 at 19:30
