我需要创建html文件并在我公开错误后保存到驱动器C：/TMP 找不到路径"C：\TMP\test.html"的一部分
我有以下代码
string fileName = @"C:\TMP\test.html";
using (FileStream fs = File.Create(fileName))
{
using (StreamWriter w = new StreamWriter(fs, Encoding.UTF8))
{
w.WriteLine("<!DOCTYPE html>");
w.WriteLine("<html>");
w.WriteLine("<head>");
w.WriteLine("<title>PChart</title>");
w.WriteLine("</p>");
w.WriteLine("</body>");
w.WriteLine("</html>");
}
}
你确定目录存在吗？在我们的代码中输入Directory.CreateDirectory：
string fileName = @"C:\TMP\BlaBla\test.html";
Directory.CreateDirectory(Path.GetDirectoryName(fileName));
using (FileStream fs = File.Create(fileName))
{
using (StreamWriter w = new StreamWriter(fs, Encoding.UTF8))
{
w.WriteLine("<!DOCTYPE html>");
w.WriteLine("<html>");
w.WriteLine("<head>");
w.WriteLine("<title>PChart</title>");
w.WriteLine("</p>");
w.WriteLine("</body>");
w.WriteLine("</html>");
}
}
我测试过，对我来说它有效
嗨，请尝试使用以下代码。如果没有文件，它将创建。但是路径应该是正确的。
string path = @"D:\TMP\test.html";
using (StreamWriter w = System.IO.File.AppendText(path))
{
w.WriteLine("<!DOCTYPE html>");
w.WriteLine("<html>");
w.WriteLine("<head>");
w.WriteLine("<title>PChart</title>");
w.WriteLine("</p>");
w.WriteLine("</body>");
w.WriteLine("</html>");
}
