I have an application that exports the result to me in a .csv file.
The export makes several project names, one of those projects has the tag name in HTML <b> .
When trying to create this file, I get an illegal character in path eror.
I have tried to put double quotes in the result:
"" + ProjectTitle + ""
But the error keeps coming up.
How could I avoid getting this error and follow the execution of my program?
Thank you very much in advance.
Using Linq, you can clean all illegal characters with a single line of code:
filename = Path.GetInvalidFileNameChars().Aggregate(filename, (current, c) => current.Replace(c.ToString(), string.Empty));
File names have a series of characters that are not allowed. among them the major and minor symbols that are used for redirection.
I would use Path.GetInvalidFileNameChars to clean characters that are not allowed from the project name. Something like this:
string GetValidFileName(string projectTitle) {
StringBuilder fileName = new StringBuilder();
List<char> invalidChars = Path.GetInvalidFileNameChars().ToList();
for (int i = 0; i < projectTitle.Length; i++) {
char c = projectTitle[i];
if (invalidChars.Contains(c))
fileName.Add('_');
else
fileName.Add(c);
}
return fileName.ToString();
}
The error is generated because there are many characters in the file names that are not allowed for fileName. For those file names in operating systems such as windows ** Only have A-Z characters, a-z, 0-9, spaces and in cases of not applying spaces use a hyphen under "_", or a simple hyphen "-"
You can try a solution a little simpler than the previous one posted.
string fileName = "ProjectTitle";
foreach (char c in System.IO.Path.GetInvalidFileNameChars())
{
fileName = fileName.Replace(c, '_');
}
This simple loop finds invalid characters in the filename and replaces them with "_"
I recommend creating paths to files with the Combine method instead of concatenating strings:
rutaCompleta = Path.Combine(nombreCarpeta, Path.GetFileName(nombreArchivo.Replace("/","\")));
