将映像上传到Azure Blob存储-本地工作，部署后失败

Question

我使用ASPNetBoilerplate作为基本框架，使用.Net Core模板，并且试图将照片上传到Blob存储。 该站点托管在Azure Web App中，并且Blob存储位于同一订阅中。

我正在使用下面的代码，当我在调试模式下本地运行时，它可以工作，但是一旦将其部署到Azure，就会出现无法找到文件D：\\ public \\ images \\的错误。

谁能看到我为azure部署所做的错误操作，或者为什么它会在本地运行但不能在Azure中运行。

我正在尝试从guid生成上传的文件名，将图像上传到azure，然后将生成的文件名存储到sql数据库中。

任何帮助或建议，将不胜感激。
