asp. net Method of Constructing Json String Using DataTable

This article illustrates how asp. net uses DataTable to construct Json strings. Share it for your reference, as follows:

/// <summary>
///  Will datatable Convert to json
/// </summary>
/// <param name="dtb"></param>
/// <returns></returns>
private string Dtb2Json(DataTable dtb) {
  JavaScriptSerializer jss = new JavaScriptSerializer();
  System.Collections.ArrayList dic = new System.Collections.ArrayList();
  foreach (DataRow dr in dtb.Rows)
  {
   System.Collections.Generic.Dictionary<string, object> drow = new System.Collections.Generic.Dictionary<string, object>();
   foreach (DataColumn dc in dtb.Columns)
   {
    drow.Add(dc.ColumnName, dr[dc.ColumnName]);
   }
   dic.Add(drow);
  }
  // Serialization 
  return jss.Serialize(dic);
} /// <summary>
///  Build JSON String 
/// </summary>
/// <param name="dt"></param>
/// <returns></returns>
public static string CreateJsonParameters(DataTable dt)
{
 System.Text.StringBuilder sb = new System.Text.StringBuilder();
 if (dt != null && dt.Rows.Count > 0)
 {
  sb.Append("[");
  for (int i = 0; i < dt.Rows.Count; i++)
  {
   sb.Append("{");
   for (int j = 0; j < dt.Columns.Count; j++)
   {
    // If the value is not last 1 Add comma separation for each 
    if (j < dt.Columns.Count - 1)
    {
     sb.Append("/"" + dt.Columns[j].ColumnName.ToString() + "/":" + "/"" + dt.Rows[i][j].ToString() + "/",");
    }
     // If the value is the last character, no comma is added 
    else if (j == dt.Columns.Count - 1)
    {
     sb.Append("/"" + dt.Columns[j].ColumnName.ToString() + "/":" + "/"" + dt.Rows[i][j].ToString() + "/"");
    }
   }
   // If it is the last 1 Words of value   No commas are added 
   if (i == dt.Rows.Count - 1)
   {
    sb.Append("}");
   }
   else
   {
    sb.Append("},");
   }
  }
  sb.Append("]");
  return sb.ToString();
 }
 else { return null; }
}

I hope this article is helpful to everyone's asp. net programming.
