我希望以编程方式找出我的应用程序是否从网络驱动器运行。最简单的方法是什么?它应该支持UNC路径(\\127.0.0.1\d$
)和映射的网络驱动器(Z:)。
我希望以编程方式找出我的应用程序是否从网络驱动器运行。最简单的方法是什么?它应该支持UNC路径(\\127.0.0.1\d$
)和映射的网络驱动器(Z:)。
这是针对映射驱动器的情况。你可以使用DriveInfo
类来判断A驱动器是否为网络驱动器。
DriveInfo info = new DriveInfo("Z");
if (info.DriveType == DriveType.Network)
{
// Running from network
}
完整的方法和示例代码。
public static bool IsRunningFromNetwork(string rootPath)
{
try
{
System.IO.DriveInfo info = new DriveInfo(rootPath);
if (info.DriveType == DriveType.Network)
{
return true;
}
return false;
}
catch
{
try
{
Uri uri = new Uri(rootPath);
return uri.IsUnc;
}
catch
{
return false;
}
}
}
static void Main(string[] args)
{
Console.WriteLine(IsRunningFromNetwork(System.IO.Path.GetPathRoot(AppDomain.CurrentDomain.BaseDirectory))); }
if (new DriveInfo(Application.StartupPath).DriveType == DriveType.Network)
{
// here
}
我重新排列了dotnetstep的解决方案,我认为这样更好,因为它避免了在传递有效路径时出现异常,并且如果传递了错误路径,则会抛出异常,这不允许做出真或假的假设。
//----------------------------------------------------------------------------------------------------
/// <summary>Gets a boolean indicating whether the specified path is a local path or a network path.</summary>
/// <param name="path">Path to check</param>
/// <returns>Returns a boolean indicating whether the specified path is a local path or a network path.</returns>
public static Boolean IsNetworkPath(String path) {
Uri uri = new Uri(path);
if (uri.IsUnc) {
return true;
}
DriveInfo info = new DriveInfo(path);
if (info.DriveType == DriveType.Network) {
return true;
}
return false;
}
测试:
//----------------------------------------------------------------------------------------------------
/// <summary>A test for IsNetworkPath</summary>

public void IsNetworkPathTest() {
String s1 = @"\\Test"; // unc
String s2 = @"C:\Program Files"; // local

String s4 = "ljöasdf"; // invalid
Assert.IsTrue(RPath.IsNetworkPath(s1));
Assert.IsFalse(RPath.IsNetworkPath(s2));
Assert.IsTrue(RPath.IsNetworkPath(s3));
try {
RPath.IsNetworkPath(s4);
Assert.Fail();
}
catch {}

return true;

DriveInfo m = DriveInfo.GetDrives().Where(p => p.DriveType == DriveType.Network).FirstOrDefault();
