在将图像发送到Google Api函数时遇到错误

        //Load the image file into memory
        var image = Google.Cloud.Vision.V1.Image.FromStream(uplFile.PostedFile.InputStream);


        // Instantiates a client
        var client = Google.Cloud.Vision.V1.ImageAnnotatorClient.Create();


        // Performs label detection on the image file
        var response = client.DetectDocumentText(image);

无法加载文件或程序集“ Google.Apis.Auth，版本= 1.21.0.0，文化=中性，PublicKeyToken = 4b01fa6e34db77ab'或其中之一依赖性。找到的程序集的清单定义不匹配程序集参考。（来自HRESULT的异常：0x80131040）

首先，我将检查您的项目文件在哪里寻找DLL。您可以通过在Visual Studio中展开依赖关系，右键单击Google.Apis.Auth依赖关系并选择属性来找到此内容。我的猜测是，它指向DLL的另一个副本，位于您计算机上其他未发布的位置。如果是这种情况，则可以通过NuGet重新安装来解决问题（它将更新项目文件中的依赖项引用）。我将通过NuGet卸载该软件包，确保已从依赖项列表中将其删除，然后重新安装。

第二，尝试将<bindingRedirect oldVersion="0.0.0.0-1.30.0" newVersion="1.30.0" />依赖项的<dependentAssembly>标签内的Google.Apis.Auth添加到您的web.config文件中。这告诉应用程序您正在使用比项目实际需要的新版本来满足依赖性。该部分应如下所示。请参见here上bindingRedirect的文档。

<dependentAssembly>
    <assemblyIdentity name="Google.Apis.Auth" publicKeyToken="xxx" cultuer="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-1.30.0" newVersion="1.30.0" />
</dependentAssembly>
