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.

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();

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.
