HTML
First we add Asp button for raise exception like below-
<asp:Button ID="btnRaiseException" Text="Click to Raise Exception" runat="server" OnClick="btnRaiseException_Click"/>
C#
Then you will need to import the following namespace.
using System.IO;
Then you button click write down below code-
protected void btnRaiseException_Click(object sender, EventArgs e)
{
try
{
int i = int.Parse("Anurag");
}
catch (Exception ex)
{
this.LogError(ex);
}
}
private void LogError(Exception ex)
{
string message = string.Format("Time: {0}", DateTime.Now.ToString("dd/MM/yyyy hh:mm:ss tt"));
message += Environment.NewLine;
message += "-----------------------------------------------------------";
message += Environment.NewLine;
message += string.Format("Message: {0}", ex.Message);
message += Environment.NewLine;
message += string.Format("StackTrace: {0}", ex.StackTrace);
message += Environment.NewLine;
message += string.Format("Source: {0}", ex.Source);
message += Environment.NewLine;
message += string.Format("TargetSite: {0}", ex.TargetSite.ToString());
message += Environment.NewLine;
message += "-----------------------------------------------------------";
message += Environment.NewLine;
string path = Server.MapPath("~/ErrorLog/ErrorLog.txt");
using (StreamWriter writer = new StreamWriter(path, true))
{
writer.WriteLine(message);
writer.Close();
}
}
