如何以编程方式找到ArcGIS版本？

是否可以使用ArcObjects.net找出计算机上安装了哪个版本的ArcGIS（即9.3。，10.0、10.1）？

在ArcObjects .NET中，使用RuntimeManager，例如：

列出所有已安装的运行时：

var runtimes = RuntimeManager.InstalledRuntimes;
foreach (RuntimeInfo runtime in runtimes)
{
  System.Diagnostics.Debug.Print(runtime.Path);
  System.Diagnostics.Debug.Print(runtime.Version);
  System.Diagnostics.Debug.Print(runtime.Product.ToString());
}

或者，仅获取当前活动的运行时：

bool succeeded = ESRI.ArcGIS.RuntimeManager.Bind(ProductCode.EngineOrDesktop);
if (succeeded)
{
  RuntimeInfo activeRunTimeInfo = RuntimeManager.ActiveRuntime;
  System.Diagnostics.Debug.Print(activeRunTimeInfo.Product.ToString());
}

同样在arcpy中，您可以使用GetInstallInfo。

在Win7 64位PC上，此注册表项可能会有所帮助。我已经安装了10.0，它显示为10.0.2414。

\ HKLM \软件\ wow6432Node \ esri \ Arcgis \ RealVersion

似乎有一个名为IArcGISVersion的接口，该接口可能带有您需要的getVersions方法。

上面与Java有关（感谢@ blah238）-这是指向.NET的链接（感谢@JasonScheirer）

您还可以通过查询AfCore.dll的版本来获取ArcGIS版本。这需要知道ArcGIS安装目录，您可以通过查询注册表或通过硬编码获得该目录（大多数用户使用C：\ Program Files（x86）\ ArcGIS \ Desktop10.3 \）。
