可执行文件的目录路径
Directory path for executable
您好,我正在尝试在我的第一个 windows 表单应用程序可执行文件中创建包含文本文档的目录文件,但是这里出了点问题:
我想让其他本地用户计算机可以使用 exe 文件:
string dir = @"C:\Users\Public\AppData\Roaming\AppFolder\document.txt";
if (!Directory.Exists(dir))
{
Directory.CreateDirectory(Path.GetDirectoryName(dir));
var stream = File.CreateText(dir);
}
但我得到了这个:
An unhandled exception of type 'System.IO.IOException' occurred in
mscorlib.dll
Additional information: The process cannot access the file
'C:\Users\Public\AppData\Roaming\AppFolder\doc.txt'
because it is being used by another process.
我想您需要发出命令才能在其他任何地方访问流
stream.Flush();
stream.Close();
尝试用using
语句拥抱CreateText
。所以在使用后关闭。 File.CreateText
将创建文件,但它在关闭之前保持打开状态。尝试打开它两次将导致 IOException
.
此代码段是 https://msdn.microsoft.com/de-de/library/system.io.file.createtext(v=vs.110).aspx
中示例的一部分
string path = @"c:\temp\MyTest.txt";
if (!File.Exists(path))
{
// Create a file to write to.
using (StreamWriter sw = File.CreateText(path))
{
sw.WriteLine("Hello");
sw.WriteLine("And");
sw.WriteLine("Welcome");
}
}
要在 AppData Roaming 文件夹中访问/创建文件/目录,您必须执行以下操作
// The folder for the roaming current user
string folder = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
// Combine the base folder with your specific folder....
string specificFolder = Path.Combine(folder, "YourSpecificFolder");
// Check if folder exists and if not, create it
if(!Directory.Exists(specificFolder))
Directory.CreateDirectory(specificFolder);
