How to convert datatable to json string using json.net?

How to convert datatable to json using json.net? Any suggestion… I ve downloaded the necessary binaries… Which class should i use to get the conversion of my datatable to json?
Thus far used this method to get json string by passing my datatable…

public string GetJSONString(DataTable table)
{
StringBuilder headStrBuilder = new StringBuilder(table.Columns.Count * 5); //pre-allocate some space, default is 16 bytes
for (int i = 0; i < table.Columns.Count; i++)
{
headStrBuilder.AppendFormat("\"{0}\" : \"{0}{1}¾\",", table.Columns[i].Caption, i);
}
headStrBuilder.Remove(headStrBuilder.Length - 1, 1); // trim away last ,
StringBuilder sb = new StringBuilder(table.Rows.Count * 5); //pre-allocate some space
sb.Append("{\"");
sb.Append(table.TableName);
sb.Append("\" : [");
for (int i = 0; i < table.Rows.Count; i++)
{
string tempStr = headStrBuilder.ToString();
sb.Append("{");
for (int j = 0; j < table.Columns.Count; j++)
{
table.Rows[i][j] = table.Rows[i][j].ToString().Replace("'", "");
tempStr = tempStr.Replace(table.Columns[j] + j.ToString() + "¾", table.Rows[i][j].ToString());
}
sb.Append(tempStr + "},");
}
sb.Remove(sb.Length - 1, 1); // trim last ,
sb.Append("]}");
return sb.ToString();
}

Now i thought of using json.net but dont know where to get started….

string json = JsonConvert.SerializeObject(table, Formatting.Indented);

Edit: You don’t need indented formatting, of course, but it makes it nice and readable.
