holding data in strings between function calls

Question

hello i have written a code like this: namespace servercommunication { public partial class Form1 : Form { static int k = 0; static string [] data = new string [150]; public void OnDataReceived( ) { string [] temp1 = new string [150]; temp1[0]=1234; if(k==0) { data[0]=temp1[0]; k++; } else { data[k]=temp1[0]; } } when the first function is called if(k==0) will executebut when second time function is called data[0] has no datai.e. it's showing .what could be the problem

I looked at your code in the context of a console mode application; I made these modifications: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace junkthis2 { class Program { public static int k = 0; public static string [] data = new string [150]; static void Main( string [] args) { OnDataReceived(); OnDataReceived(); OnDataReceived(); OnDataReceived(); Console .Read(); } public static void OnDataReceived() { string [] temp1 = new string [150]; temp1[0] = 1234 ; if (k == 0) { data[0] = temp1[0]; k++; } else { data[k] = temp1[0]; k++; // added } Console .WriteLine(

Temp ); for ( int i = 0; i { if (! string .IsNullOrEmpty(temp1[i])) Console .WriteLine(i.ToString() + )  + temp1[i]); } Console .WriteLine(

Data ); for ( int j = 0; j { if (! string .IsNullOrEmpty(data[j])) Console .WriteLine(j.ToString() + )  + data[j]); } } } } It runs and seems to work. It produced this result: Temp 0) 1234 Data 0) 1234 Temp 0) 1234 Data 0) 1234 1) 1234 Temp 0) 1234 Data 0) 1234 1) 1234 2) 1234 Temp 0) 1234 Data 0) 1234 1) 1234 2) 1234 3) 1234
