Hello everyone,

I want to put values inside array in if statement. so I declared an array

string[] ar = new ar[5];


if (x=="10)
ar={"c", "d", "e","f"}
else
ar={"a", "b", "c","d"}

this gives me an error Invalid expression term "{"

can anyone tell me what am I doing wrong.

Try:

if (x=="10)
ar= new string[] {"c", "d", "e","f"};
else
ar=new string[] {"a", "b", "c","d"};

Note the addition of the "new" operator, along with semicolons.

Vinki,

This syntax isn't available until C# 3.0. The only way you will get
this to work is if you are using VS.NET Orcas (which is currently in beta
right now).

Yeah, but using the new keyword, it will work in any version :)

ar = new string[] { "c", "d", "e", "f" };

Also, there is an error in the if statement...missing a quote:

if (x == "10") ...

Lastly, these are all chars in the example so the OP may want to declare the
array as a character array instead of string...:

char[] ar;
if (x == "10") {
ar = new char[] { 'c', 'd', 'e', 'f' };
} else {
ar = new char[] { 'a', 'b', 'd', 'e' };
}

HTH,
