How Do I: Extract value from string[]

Gustavo

Hello:

I have a string[] and need to extract the fields. Can someone tell me how?

string[] Fields = { "File_ID, File_ID_Sub, Update_ID" };

fpor example what do I do if I need to get the 2nd field? How can I put it in a for loop to get all of them? How can I get the count of fields?

hi ..

this will considered as single item in the array..

because whole sentence in the array in within the single "......"

so if you want to create multiple fields you have to declared them as separate "" like

string[] Fields = { "File_ID" , "File_ID_Sub" , "Update_ID" };

now to extract elements you can use

fields[0] for File_ID
fields[1] for File_ID_Sub and so on

to get the field count you can use Fields.Length

in for loop

for (int i = 0; i < Fields.Length; i++)
   {
   Response.Write(" " + Fields[i] + "
");
   }

if it help you them plz mark my answer

Thanks, it works now.

1) I was using the 'Count' instead of 'Length'.
2) I had: {"File_ID, File_ID_Sub, Update_ID"} instead of: { "File_ID" , "File_ID_Sub" , "Update_ID" }; I did not qoute each of the fields... LOL

HI,
Use foreach loop like below
string[] Fields = { "File_ID", "File_ID_Sub", "Update_ID" };
            foreach (string s in Fields)
            {
                Console.WriteLine(s);
            }
