Hello friends,
I done a small program which i pasted below iam getting error in this line if(fail.Length =3). I dono how to get the array values size not length.So please me....
string[] a=new string[5];
 By using Length method we can get length ie 6 as a output...But if i stored three string values how to get that value number...

Please help me out.....

<% 
String Result="hello dude nvo what is ur problem nvo match today is it vow nvo match for its gud ya k then nvo entries";
int[] Resultt = new int[6];
string[] pass =new string[6];
string[] fail =new string[6];
String a = "available";
String b="unavailable";

string[] datas = new string[]
        {
            "no",
            "no match",
            "no match for",
            "no entries",           
        };
for(int i = 0; i <= 3; i++)
{
Resultt[i] = Result.IndexOf(datas[i]);
}
for (int i = 0; i <= 3; i++)
{
    if (Resultt[i] != -1)
    {
        //Response.Write("available");
  
  for(int j=0; j<=3; j++)
  {
  pass[j] = a;
  }
  
    }
    else
    {
        //Response.Write("unavailable");
  
  for(int k=0; k<=3; k++)
  {
  fail[k] = b;
  }
    }
 if(fail.GetLength =3)
 //if(fail.Length =3)
 //if(sizeof(fail) =3)
 {
 Response.Write("unavailable");
 }
 else
 {
 Response.Write("available");
 }
}

 I'm not quite sure what you are trying to do because the length of fail is 6 (you have set that when you assigned the new string[6] in the declaration of fail). 

But, when you compare you need to use == and not =.  A single = is for assignment.  A double == is for comparison.  So fail.Length==3 is false but fail.Length==6 is true.

Let us know what you are really trying to do if you need more help.
