Slightly more detail with how to use folders and to grant all users read-only access. Html:

关于如何使用文件夹和授予所有用户只读访问权限的更详细的说明。Html:

C#

HttpPostedFileBase file = Request.Files[0];
   if (file.ContentLength > 0) // accept the file
        {
            string accessKey = "XXXXXXXXXXX";
            string secretKey = "122334XXXXXXXXXX";
            AmazonS3 client;

Most likely this is a Base64-encoded string, but you should check the S3 documentation to be sure. If it is, you should use Convert.ToBase64String() and pass it the byte array.

很可能这是一个base64编码的字符串，但是您应该检查一下S3文档以确定。如果是，您应该使用Convert.ToBase64String()并将字节数组传递给它。

Here's some sample code you can try. I haven't tested it, but it should help you get the right idea:

下面是一些您可以尝试的示例代码。我还没有测试过，但它应该能帮助你找到正确的想法:

if (Request.Files.Count >= 1) {
    var file = Request.Files[0];
    var fileCOntents= new byte[file.ContentLength];
    file.InputStream.Read(fileContents, 0, file.ContentLength);
    var fileBase64String = Convert.ToBase64String(fileContents);

    // now you can send fileBase64String to the S3 uploader
}
