I have a ASP.Net web handler that returns results of a query in JSON format

public static String dt2JSON(DataTable dt)
{
    String s = \"{\\\"rows\\\":[\";

    I think you should rather look at the JavaScriptSerializer class. It's a lot more stable, and will correctly handle any kind of data or escape characters etc. Also, your code will look a lot cleaner.

    In your case your class can look like this:

    public static String dt2JSON(DataTable dt) {
    var rows = new List();
    foreach(DataRow row in dt.Rows)
    {
        var rowData = new Dictionary();
        foreach(DataColumn col in dt.Columns)
            rowData[col.ColumnName] = row[col];
        rows.Add(rowData);
    }
    var js = new JavaScriptSerializer();
    return js.Serialize(new { rows = rows });
}



    This method will return a correctly serialized json string... For example, sth like this:
    


    {"rows":[{"id":1,"name":"hello"},{"id":2,"name":"bye"}]}

    


    Have fun! :)
