c# - 从 GAC 在 C# 代码中卸载

Question

如何从我的 C# 应用程序中卸载 GAC。

我无法从 GAC 卸载特定的 exe 和 DLL。

在 C# 中卸载 GAC 是正确的方法吗？

public void RemoveAssembly(string ShortAssemblyName, string PublicToken)
{
    AssemblyCacheEnum AssembCache = new AssemblyCacheEnum(null);

    string FullAssembName = null;

    for (; ; )
    {
        string AssembNameLoc = AssembCache.GetNextAssembly();
        if (AssembNameLoc == null)
            break;

        string Pt;
        string ShortName = GetAssemblyShortName(AssembNameLoc, out Pt);

        if (ShortAssemblyName == ShortName)
        {

            if (PublicToken != null)
            {
                PublicToken = PublicToken.Trim().ToLower();
                if (Pt == null)
                {
                    FullAssembName = AssembNameLoc;
                    break;
                }

                Pt = Pt.ToLower().Trim();

                if (PublicToken == Pt)
                {
                    FullAssembName = AssembNameLoc;
                    break;
                }
            }
            else
            {
                FullAssembName = AssembNameLoc;
                break;
            }
        }
    }

    string Stoken = "null";
    if (PublicToken != null)
    {
        Stoken = PublicToken;
    }

    if (FullAssembName == null)
        throw new Exception("Assembly=" + ShortAssemblyName + ",PublicToken=" + 
        token + " not found in GAC");

    AssemblyCacheUninstallDisposition UninstDisp;


    AssemblyCache.UninstallAssembly(FullAssembName, null, out UninstDisp);
}


public static void UninstallAssembly(String assemblyName, InstallReference reference, out AssemblyCacheUninstallDisposition disp)
{
    AssemblyCacheUninstallDisposition dispResult = AssemblyCacheUninstallDisposition.Uninstalled;
    if (reference != null)
    {
        if (!InstallReferenceGuid.IsValidGuidScheme(reference.GuidScheme))
            throw new ArgumentException("Invalid reference guid.", "guid");
    }

    IAssemblyCache ac = null;

    int hr = Utils.CreateAssemblyCache(out ac, 0);
    if (hr >= 0)
    {
        hr = ac.UninstallAssembly(0, assemblyName, reference, out dispResult);
    }

    if (hr < 0)
    {
        Marshal.ThrowExceptionForHR(hr);
    }

    disp = dispResult;
}

假设 DLL 与运行此代码的目录位于同一目录中，请尝试:

ArrayList libraries = new ArrayList();
libraries.Add("somedll1.dll");
libraries.Add("somedll2.dll");

Console.WriteLine("Registering DDLs in the Gac");

try
{
    for (int i = 0; i < libraries.Count; i++)
    {
        // get the path from the running exe, and remove the running exe's name from it
        new System.EnterpriseServices.Internal.Publish().GacRemove(System.Reflection.Assembly.GetExecutingAssembly().Location.Replace("ThisUtilitiesName.exe", "") + libraries[i]);
    }

    Console.WriteLine("Completed task successfully");
}
catch (Exception exp)
{
    Console.WriteLine(exp.Message);
}

希望这对某人有帮助...
