Azure 错误 访问路径被拒绝

Question

部署后，我尝试使用将 pdf 文件存储到目录

string biodataPath = Server.MapPath("~/Content/UserImages/");

string fullBiodataPath = Path.Combine(biodataPath, guid.ToString() + extension);

但我收到错误

Could not find a part of the path 'D:\home\site\wwwroot\Content\UserImages\6d8938df-aa4f-40e4-96e3-b2debb6ed992.png'

通过 ftp 连接后，我在 wwwroot 中添加了 Content\UserImages 目录。怎么解决这个问题？

Answer 1

I have added Content\UserImages directory in wwwroot afer connecting through ftp. How to solve this?

如果该目录不存在，您可以尝试创建该目录。

string biodataPath = Server.MapPath("~/Content/UserImages/");

if (!Directory.Exists(biodataPath))
{
    DirectoryInfo di = Directory.CreateDirectory(biodataPath);
}

此外，如果可能的话，您可以将静态文件存储在 Azure Blob storage 中.

编辑:我将源图像 SourceImg.png 放在 UserImages 文件夹中，我可以将源文件读入字节数组并将其写入另一个 FileStream。

string biodataPath = Server.MapPath("~/Content/UserImages/");
string pathSource = biodataPath + "SourceImg.png";

//the following code will create new file named 6d8938df-aa4f-40e4-96e3-b2debb6ed992.png
string pathNew = Server.MapPath("~/Content/UserImages/") + "6d8938df-aa4f-40e4-96e3-b2debb6ed992.png";

try
{

    using (FileStream fsSource = new FileStream(pathSource,
        FileMode.Open, FileAccess.Read))
    {
        byte[] bytes = new byte[fsSource.Length];
        int numBytesToRead = (int)fsSource.Length;
        int numBytesRead = 0;
        while (numBytesToRead > 0)
        {
            int n = fsSource.Read(bytes, numBytesRead, numBytesToRead);

            if (n == 0)
                break;

            numBytesRead += n;
            numBytesToRead -= n;
        }
        numBytesToRead = bytes.Length;

        // Write the byte array to the new FileStream.
        using (FileStream fsNew = new FileStream(pathNew,
            FileMode.Create, FileAccess.Write))
        {
            fsNew.Write(bytes, 0, numBytesToRead);
        }
    }
}
catch (FileNotFoundException ioEx)
{
    Console.WriteLine(ioEx.Message);
}

如果我检查 UserImages 文件夹，我会发现 6d8938df-aa4f-40e4-96e3-b2debb6ed992.png 已创建。
