Directory is locked after creation of file while program is running

Question

After I created a file in a directory the directory is locked as long as my program which created the file is running. Is there any way to release the lock? I need to rename the directory couple of lines later and I always get an IOException saying "Access to the path "..." denied".

Directory.CreateDirectory(dstPath);
File.Copy(srcPath + "\\File1.txt", dstPath + "\\File1.txt"); // no lock yet
File.Create(dstPath + "\\" + "File2.txt"); // causes lock

File.Create(string path) Creates a file and leaves the stream open.

you need to do the following:

Directory.CreateDirectory(dstPath);
File.Copy(srcPath + "\\File1.txt", dstPath + "\\File1.txt");
using (var stream = File.Create(dstPath + "\\" + "File2.txt"))
{
    //you can write to the file here
}

The using statement asures you that the stream will be closed and the lock to the file will be released.

Hope this helps
