應用.NET 4的框架編譯不會Server 2012的

Question

上運行我編譯應用程序使用的.NET Framework 4，因爲我需要這在XP和Server 2003不支持.NET框架4.5的工作。問題是，現在運行良好的XP和2003點的服務器，但不是我的服務器上2012 Server 2012中具有.NET 4.5，從我讀過.NET 4.5是在.NET 4

它下面的錯誤向後兼容我收到我的2012服務器上：如果您單擊繼續，應用程序將忽略此錯誤並嘗試繼續

---

未處理的異常發生在您的應用程序。如果您單擊退出，應用程序將立即關閉。

該系統找不到指定的文件。

************** JIT Debugging ************** 
To enable just-in-time (JIT) debugging, the .config file for this 
application or computer (machine.config) must have the 
jitDebugging value set in the system.windows.forms section. 
The application must also be compiled with debugging 
enabled. 

For example: 

<configuration> 
    <system.windows.forms jitDebugging="true" /> 
</configuration> 

When JIT debugging is enabled, any unhandled exception 
will be sent to the JIT debugger registered on the computer 
rather than be handled by this dialog box.

這裏是被稱爲此時代碼：

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

我強烈懷疑這無關，與.NET的版本，正在使用。畢竟，從堆棧跟蹤，你可以清楚地看到你的代碼是執行：

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

我懷疑，問題是權限之一 - 無論你正在試圖做在Windows Server 2012中失敗由於它運行在更加鎖定的環境中。

或者，它可能是你試圖啓動您的開發機器存在一個過程，而不是在服務器上。如果沒有看到代碼，我們無法確定 - 但您應該仔細查看DirectoryExporter_Click中正在執行的操作，特別是在撥打Process.Start時。檢查您嘗試運行的可執行文件，然後檢查它是否存在於服務器上，並且您正在運行的用戶有權執行它。

Answer 2

我通過編輯代碼解決了這個，如下圖所示：

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);
