Illegal Characters in Path when extracting zip file with C#

问题

I'm trying to write a method that extracts a zip file to a directory, finds a file in the extracted contents, reads the text in that file to a string, and returns that string. Here is my attempt

private string _getDataFile(string zipFile)
{

    string pathToFolder = @"C:\Path\To\The\File";

    foreach (char c in Path.GetInvalidPathChars())
    {
        pathToFolder = Regex.Replace(pathToFolder, c.ToString(), "");
    }
    string pathToFile = pathToFolder + @"\model.dat";
    ZipFile.ExtractToDirectory(zipFile, pathToFolder);
    string dataToReturn = File.ReadAllText(pathToFile);
    return dataToReturn;
}

However, despite my foreach loop replacing illegal path characters, the program still throws an illegal characters in path exception at the ZipFile.ExtractToDirectory line no matter what directory I try to use and I have no idea why. Any help would be greatly appreciated.

回答1:

According to a similar post, it looks like you may have a problem with a file name inside the target zip file; it is not a problem with your specified zip file name or directory. Try extracting the contents of the file manually to see if there are unusual file names.

You can iterate through all the entries and sanitize the filenames before extracting them by using this snippet that I wrote here: ZipFile.ExtractToDirectory "Illegal characters in path"
