HI,

i am in a deep trouble.

here i have declared a string array..

        int arrayCount = Convert.ToInt32(Session["VersionIds"].ToString().Split(',').Length - 1);
      
        string[] versions = new string[arrayCount];

in this array, i wanna check wheather a string is there or not...

if it dosent exists i wanna add that string to the string array......

for that i tried to use

version[arrayCount].Contains(..........);

but this is thowing an exception...... index out of range..

can anyone please tell me how cann i solve this issue... 

string []arrString = "Hello ASp.net Brothers".Split(" ").ToCharArray();

foreach(string str in arrString)
{
  
   if(str.Equals("your strin to comapre")
    {
/ //   Do something 
     }

}

I hope this snippet will help you

 First error (index out of range is solvable doing this:

version[arrayCount - 1].Contains(..........);

Check possibility: 

bool found=false;

Hi,

It would be troublesome to add to array, as it is fixed size, instead it would be easier to use arraylist. Here is the code you are looking for:-

ArrayList al = new ArrayList();
al.Add("hello");
al.Add("abcd");
al.Add("This");
al.Add("Is");
al.Add("My");
al.Add("New");
al.Add("ArrayList");
al.Add("Control");
for (int i = 0; i <= al.Count - 1; i++) {
 if (al.Item(i).ToString == "hello")
 {
  continue;
 }
 else
 {
  al.Add(al.Item(i).ToString);
 }

}
for (int j = 0; j <= al.Count - 1; j++) {
 Response.Write((string)al.Item(j));
 Response.Write("&nbsp;<->&nbsp;");
}

 Try this code:

        string[] arr = new string[3];
        arr[0] = "India";
        arr[1] = "America";
        arr[2] = "China";
        for (int i = 0; i < arr.Length; i++)
        {
            if (arr[i] == "China")
            {
			//----------------your code here-----------------
            }
        } 

satalaj:

string []arrString = "Hello ASp.net Brothers".Split(" ").ToCharArray();

foreach(string str in arrString)
{
  
   if(str.Equals("your strin to comapre")
    {
/ //   Do something 
     }

}

in the first strp itself i wanna check :

 if(str.Equals("your strin to comapre")

{

if false--- it should go inside.. when ever the string exists in the array, it shoul;d not do anything.

that is if the araay does nt contain the string which we are comparing, it should go inside.... else nothing...

} 

Hi,

private void Button1_Click(object sender, System.EventArgs e)
{
 void[] arr;
 string str;
 str = "sample text contains commas and this can be done in this way";
 arr = str.Split(" ".ToCharArray);
 object compstring = "commas";
 for (int i = 0; i <= (arr.Length) - 1; i++) {
  if ((string.Compare(arr(i), compstring)) == 0)
  {
   MsgBox("String is Equal");
  }
 }
}

hello, for this purpose you should declare a List<string> instead of an array, this allow you to search for elements, you cna later convert the list to an array if for any particular reason you really need an array.

Hi,

The count of array is arrayCount. So the first item is version[0] and the last item is version[arrayCount-1].

version[arrayCount] is out of range so as to throw a error. The number should be no more than arrayCount-1.

Hope it helps.

 try this out

versions.contains(....);
