I am currently using Renci SSH.NET to upload files and folders to a Unix Server using SFTP, and creating directories using
sftp.CreateDirectory("//server/test/test2");
works perfectly, as long as the folder "test" already exists. If it doesn't, the CreateDirectory
method fails, and this happens everytime when you try to create directories containing multiple levels.
Is there an elegant way to recursively generate all the directories in a string? I was assuming that the CreateDirectory
method does that automatically.
There's no other way.
Just iterate directory levels, testing each level using SftpClient.GetAttributes
and create the levels that do not exist.
static public void CreateDirectoryRecursively(this SftpClient client, string path)
{
string current = "";
if (path[0] == '/')
{
path = path.Substring(1);
}
while (!string.IsNullOrEmpty(path))
{
int p = path.IndexOf('/');
current += '/';
if (p >= 0)
{
current += path.Substring(0, p);
path = path.Substring(p + 1);
}
else
{
current += path;
path = "";
}
try
{
SftpFileAttributes attrs = client.GetAttributes(current);
if (!attrs.IsDirectory)
{
throw new Exception("not directory");
}
}
catch (SftpPathNotFoundException)
{
client.CreateDirectory(current);
}
}
}
