How can i optimize this c# code?
- by Pandiya Chendur
I have converted my Datatable to json string use the following method...
public string GetJSONString(DataTable Dt)
{
string[] StrDc = new string[Dt.Columns.Count];
string HeadStr = string.Empty;
for (int i = 0; i < Dt.Columns.Count; i++)
{
StrDc[i] = Dt.Columns[i].Caption;
HeadStr += "\"" + StrDc[i] + "\" : \"" + StrDc[i] + i.ToString() + "¾" + "\",";
}
HeadStr = HeadStr.Substring(0, HeadStr.Length - 1);
StringBuilder Sb = new StringBuilder();
Sb.Append("{\"" + Dt.TableName + "\" : [");
for (int i = 0; i < Dt.Rows.Count; i++)
{
string TempStr = HeadStr;
Sb.Append("{");
for (int j = 0; j < Dt.Columns.Count; j++)
{
if (Dt.Rows[i][j].ToString().Contains("'") == true)
{
Dt.Rows[i][j] = Dt.Rows[i][j].ToString().Replace("'", "");
}
TempStr = TempStr.Replace(Dt.Columns[j] + j.ToString() + "¾", Dt.Rows[i][j].ToString());
}
Sb.Append(TempStr + "},");
}
Sb = new StringBuilder(Sb.ToString().Substring(0, Sb.ToString().Length - 1));
Sb.Append("]}");
return Sb.ToString();
}
Is this fair enough or still there is margin for optimization to make it execute faster.... Any suggestion...
