Simple Error Log Creator

1. Add This as Common in Your Application.

public static void WriteError(string errorMessage)

{

try

{

string path = "~/LogFile/" + DateTime.Today.ToString("dd-MM-yy") + ".txt";

if (!File.Exists(System.Web.HttpContext.Current.Server.MapPath(path)))

{

File.Create(System.Web.HttpContext.Current.Server.MapPath(path)).Close();

}

using (StreamWriter w = File.AppendText(System.Web.HttpContext.Current.Server.MapPath(path)))

{

w.WriteLine("\r\nLog Entry : ");

w.WriteLine("{0}", DateTime.Now.ToString(CultureInfo.InvariantCulture));

string err = "Error in: " + System.Web.HttpContext.Current.Request.Url.ToString() +

". Error Message:" + errorMessage;

w.WriteLine(err);

w.WriteLine("__________________________");

w.Flush();

w.Close();

}

}

catch (Exception ex)

{

WriteError(ex.Message);

}

}

2. ErrorLog is as Class Name. (Example --> Below)

How to Convert XML String to XML and Get Values With LINQ

XDocument XMLdoc = XDocument.Parse(XMLString);

try

{

string body;

string CcMailid = "";

string Path = Server.MapPath("~/Imgs/Logo.gif");

string rootUrl = Page.Request.ServerVariables["HTTP_HOST"].ToString() + RequestDetails;

var XMLVales = (from _Doc in XMLdoc.Descendants("Product")

select new

{

ProductName = _Doc.Element("ProductName").Value,

Amount = _Doc.Element("ProductAmt").Value,

TotalAmount = _Doc.Element("ProductTotalAmt").Value

}).Last();

body = ObjHtmlBody.BodyContentNew(RequesterName, SubmitterName, ReqId, XMLVales.ProductName, XMLVales.Quantity, XMLVales.Amount, XMLVales.TotalAmount, rootUrl);

string[] _ReqCode = ddlRequestFrom.SelectedValue.Split('^');

if (Convert.ToString(Session["EmpCode"]) != Convert.ToString(_ReqCode[0]))

{

CcMailid = _ReqCode[1].Trim();

}

ObjSendMail.SendEmail(ToMailId, CcMailid, "New Requst", body, Path);

}

catch (Exception Ex)

{

ErrorLog.WriteError("FrmRequest() --> : buildAndSendEmail() : --> " + Ex);

}

How to check IN Clause Condition in LINQ

List<int> ObjCircleList = null;

ObjCircleList = new List<int>();

for (int i = 0; i < ddlCircle.SelectedValue.Split(',').Count(); i++)

{

ObjCircleList.Add(Convert.ToInt32(ddlCircle.SelectedValue.Split(',')[i]));

}

string CentreNames = "", CentreIds = "";

foreach (Center c in Dbi.Contactss.ListContacts(db, 10).Where(p => ObjCircleList.Contains(p.CorpCenterId)).OrderBy(p => p.Center_name))

{

CentreNames = CentreNames + c.Center_name.Trim().TrimEnd() + "|";

CentreIds = CentreIds + c.id.ToString() + "|";

}
