下面我们看看DataTableToJson这个方法的代码，这个比较简单，我也是看它的帮助文档写出来的，代码的详细说明就不说了。
public static string DataTableToJSON(DataTable dt, string tableName, int pageCount)
{
StringBuilder sb = new StringBuilder();
StringWriter sw = new StringWriter(sb);
using (JsonWriter jw = new JsonTextWriter(sw))
{
JsonSerializer ser = new JsonSerializer();
jw.WriteStartObject();
jw.WritePropertyName(tableName);
jw.WriteStartArray();
#region TableName属性
foreach (DataRow dr in dt.Rows)
{
jw.WriteStartObject();
foreach (DataColumn dc in dt.Columns)
{
jw.WritePropertyName(dc.ColumnName);
ser.Serialize(jw, dr[dc].ToString());
}
jw.WriteEndObject();
}
#endregion
jw.WriteEndArray();
jw.WriteEndObject();
sw.Close();
jw.Close();
}
return sb.ToString();
}

$("#Pagination").pagination(<%=pageCount %>这个就是起到了记录总数的作用。
