应用.NET 4的框架编译不会Server 2012的

Question

上运行我编译应用程序使用的.NET Framework 4，因为我需要这在XP和Server 2003不支持.NET框架4.5的工作。问题是，现在运行良好的XP和2003点的服务器，但不是我的服务器上2012 Server 2012中具有.NET 4.5，从我读过.NET 4.5是在.NET 4

它下面的错误向后兼容我收到我的2012服务器上：如果您单击继续，应用程序将忽略此错误并尝试继续

未处理的异常发生在您的应用程序。如果您单击退出，应用程序将立即关闭。

该系统找不到指定的文件。

To enable just-in-time (JIT) debugging, the .config file for this

这里是被称为此时代码：

public string get_regValue(string userroot, string subkey, string keyname, string app) 
     { 
      string userRoot = userroot; 
      string subKey = subkey; 
      string keyName = userRoot + "\\" + subKey; 

      string regValue = (string)Registry.GetValue(keyName, keyname, null); 
      regValue = regValue + app; 

      return regValue; 
     } 

     private void DirectoryExporter_Click(object sender, EventArgs e) 
     { 
      // Button to Launch the Directory Exporter 
      string regKey; 
      RegistryKey openKey = Registry.LocalMachine.OpenSubKey("HKEY_LOCAL_MACHINE\\SOFTWARE\\Wow6432Node\\Dell"); 
      // Checks for key, if null (empty) get 32 bit key 
      if (openKey == null) 
      { 
       // 32 bit key 
       regKey = "HKEY_LOCAL_MACHINE\\SOFTWARE\\Dell"; 
      } 
      else 
      { 
       // 64 bit key 
       regKey = "HKEY_LOCAL_MACHINE\\SOFTWARE\\Wow6432Node\\Dell"; 
      } 

      var regvalue = get_regValue(regKey, "Migrator for GroupWise", "AdminInstallDir", "gwdirapp.exe"); 
      Process.Start(@regvalue); 
     } 

Answer 1

我强烈怀疑这无关，与.NET的版本，正在使用。毕竟，从堆栈跟踪，你可以清楚地看到你的代码是执行：

at MyApplication.Form1.DirectoryExporter_Click(Object sender, EventArgs e) 

我怀疑，问题是权限之一 - 无论你正在试图做在Windows Server 2012中失败由于它运行在更加锁定的环境中。

或者，它可能是你试图启动您的开发机器存在一个过程，而不是在服务器上。如果没有看到代码，我们无法确定 - 但您应该仔细查看DirectoryExporter_Click中正在执行的操作，特别是在拨打Process.Start时。检查您尝试运行的可执行文件，然后检查它是否存在于服务器上，并且您正在运行的用户有权执行它。

我通过编辑代码解决了这个，如下图所示：

public string get_regValue(string userroot, string subkey, string keyname, string app) 
{ 
    string userRoot = userroot; 
    string subKey = subkey; 
    string keyName = userRoot + "\\" + subKey; 

    string regValue = (string)Registry.GetValue(keyName, keyname, null); 
    regValue = regValue + app; 

    return regValue; 
} 

private void DirectoryExporter_Click(object sender, EventArgs e) 
{ 
    // Button to Launch the Directory Exporter 
    string regKey; 
    RegistryKey openKey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\\Wow6432Node\\Dell"); 
    // Checks for key, if null (empty) get 32 bit key 

    if (openKey == null) 
    { 
     // 32 bit key 
     regKey = "HKEY_LOCAL_MACHINE\\SOFTWARE\\Dell"; 
    } 
    else 
    { 
     // 64 bit key 
     regKey = "HKEY_LOCAL_MACHINE\\SOFTWARE\\Wow6432Node\\Dell";     
    } 

    var regvalue = get_regValue(regKey, "Migrator for GroupWise", "AdminInstallDir", "gwdirapp.exe"); 
    Process.Start(regvalue);
