取Managed Assembly版本号

这个方法不仅仅可以取执行文件，也可以取DLL的版本号，支持所有托管的Assembly。

public string GetAppVersion(string appName)

{
try
{
Assembly assembly = Assembly.LoadFrom(appName + ".exe");
return assembly.GetName().Version.ToString();

}
catch (Exception e)

{
Logger.Instance.LogException(e, "Load Assembly fail");

}
return "Unknown";

}

取Native生成文件版本号

如果文件是使用Native code生成出来的，就没有那么简单了。

public string GetNativeAppVersion(string appName)

{
try
{
FileVersionInfo versionInfo = FileVersionInfo.GetVersionInfo(appName+ ".exe");
StringBuilder versionNumber = new StringBuilder();

versionNumber.Append(versionInfo.ProductMajorPart);

versionNumber.Append(".");

versionNumber.Append(versionInfo.ProductMinorPart);

versionNumber.Append(".");

versionNumber.Append(versionInfo.ProductBuildPart);

versionNumber.Append(".");

versionNumber.Append(versionInfo.ProductPrivatePart);

return versionNumber.ToString();

}
catch (FileNotFoundException e)

{
Logger.Instance.LogException(e, "Fail to find the File");

}
catch (Exception e)

{
Logger.Instance.LogException(e, "Fail to get native application version");

}
return "Unknown";

}

类，取出Native文件的版本信息。下面代码修改自OpenNETCF Smart Device Framework v 1.4 的FileVersionInfo类。
