Hi, I am creating error log -

public void GetErrorFile(string source, string errormessage)

{

string filename = "C:\\Error_" + DateTime.Now.ToString("dd-MM-yyyy") + ".txt";

if (File.Exists(filename))

{

using (StreamWriter writer = new StreamWriter(filename, true))

{

writer.WriteLine("Time: " + DateTime.Now);

writer.WriteLine("Source: " + source);

writer.WriteLine("Error: " + errormessage);

writer.WriteLine(" ");

}

else

{

StreamWriter writer = File.CreateText(filename);

writer.WriteLine("Time: " + DateTime.Now);

writer.WriteLine("Source: " + source);

writer.WriteLine("Error: " + errormessage);

writer.WriteLine(" ");

writer.Close();

}

but while creating new error log i am getting error -

Could not find a part of the path 'my path'.....

I am not getting why this error is coming?

Accepted answer
here it is

public void GetErrorFile(string source, string errormessage)
{
string filename = "C:\\Error_" + DateTime.Now.ToString("dd-MM-yyyy") + ".txt";
StringBuilder sb=new StringBuilder();
sb.AppendLine("Time: " + DateTime.Now);
sb.AppendLine("Source: " + source);
sb.AppendLine("Error: " + errormessage;
File.AppendAllText(filename,sb.ToString);

}

ok..you can use these code as it will not using stream object. Therefore it will be fast.

Hi,
Try like this

public void GetErrorFile(string source, string errormessage)
{
string filename = "C:\\Error_" + DateTime.Now.ToString("dd-MM-yyyy") + ".txt";
using(StringBuilder sb=new StringBuilder())
{
sb.AppendLine("Time: " + DateTime.Now);
sb.AppendLine("Source: " + source);
sb.AppendLine("Error: " + errormessage;
File.AppendAllText(filename,sb.ToString);
}
}
