It's not an anonymous array, it's simply an int array

int[]

What do you mean by assign as runtime?

thanks for your reply

actually i have one list

            List<string> lstClm = new List<string>();
            lstClm.Add("institutionid");
            lstClm.Add("institutionname");
            lstClm.Add("displayname");
            lstClm.Add("shortname");
            lstClm.Add("supportedfield");
            lstClm.Add("schemename");
            lstClm.Add("subscriptionto");

i want to assign these list values to that array variable one by one through for loop.

• var data3 = new[]

• {

• for(int i=0;i<lstClm.length;i++)
• {

• lstClm[i],

• }

• }

is it possible?

finally i want like this

data3 = new[] { "institutionid", "institutionname","displayname","shortname","supportedfield","schemename","subscriptionto"}

var data3 = lstClm.ToArray();

Don't be confused by "var".  Just do

string[] data3

var does not making something anonymous, in the case of what you're doing Visual Studio works out the type for you.  It can work this out from

var x = new []{1,2,3}

because it knows it is an array of ints, but it can't work it out from

var x = new [];

However the list you are getting data from is string so your variable has to be an array of string so just declare it as such.

string[] x;

People use var wrongly all the time and in situations like this is can cause problems.
