Why do you do this :
if (validFileName.Length > 160) //safe value threshold is 260
validFileName = validFileName.Remove(156) + "..." return validFileName + "." + extension;
}
?

In my case I only need 160 characters as file name, so I remove everthing after 156 characters and append it with "...". Also, some systems based on the filesystem won't allow more than 256 char, so its safe to restrict the length.

Hi, I came here to look for a solution. The above code was not necessarily what I was looking for. What I wanted to do was if I had a string such as 'desktop/newfolder/file.html' I would want to convert this string to 'file.html'.

I wrote my own code that worked for this problem. I just thought I would share with you all :

private string CreateValidFileName(string title)
{
// remove all white spaces
title = title.Trim();

string validFileName = title;

// loop through the length of the string
for (int i = 0; i < title.Length; i++)
{
// if the current string is a '/'
if(title[i] == '/')
{
// set the valid file to all characters after the '/'
validFileName = title.Substring(i, (title.Length - i));
}
}

// remove the front '/' ex. ( file name of '/file.swf' would be 'file.swf' )
validFileName = validFileName.Remove(0, 1);

// Return the Valid filename
return validFileName;
}






Just copy and paste the code and it will work. Hope this helps someone with the same issue
