insert array in database

What database are you using?

if u r using sqlserver, it should be easy.
Before sending it to database traverse the array and make a single string with array values in a "," or ":" then save the string as varchar into database. When u need to fetch the data u just have to break it into substrings..

Saving arrays in a database as any kind of delimited field is usually not a good idea. The point of databases is normalization. Why don't you save the array as individual rows in a detail table and join it to the primary table?

The implementation of that depends on which rdbms you are using.

thanks for the reply guys .I got that part working but when i inserting values in databse i get this exception error Incorrect syntax near '/'.Can anyone help me with this.I am sure that i dont have this sysmbol anywhere in my string or text.Thanks

can you post your code so we may analyse and tell you.

sorry i knew what the problem was the problem now is i am getting error Index was outside the bounds of the array.my code is as follows

private void saveDataInDatabase()
        {
            string[] key = null;
            for (int i = 0; i < allData.Count; i++)
            {
                
                TextProcItem item = (TextProcItem)allData[i];
                string text1 = item.text.ToString();
                text1 = text1.Replace("'", "''");
                string sent2 = item.sentences.ToString();
                sent2 = sent2.Replace("'", "''");

My answer is absolutely not. These are two completely different data structures. There are work around like putting it in a blob (serialization) or comma separating a text column but you don't to access the the individual values in your queries.

NOTE: Use parametrized query.
