在Amazon S3上上传图像.源代码

我正在尝试在Amazon s3上上传图像。我尝试过不同的源代码，但没有白费。我坚持区分IAmazonClient, Amazons3对象等。谁能给我举个例子，指导我如何在s3上上传图像。我正在开发REST服务，可以捕获图像并在amazon s3上上传。

• 我的桶在澳大利亚悉尼。
• http://irisdb.s3apsoutheast2。amazonaws.com/
• accesskey = "xxxxxxxx"
• secretKey = "cxxxxxxxxx"

• 端点:irisdb.s3websiteapsoutheast2。amazonaws.com

      string accessKey = "xxxx";
      string secretKey = "mxxxxx";
      string bucketName = "irisdb"; // Set to a bucket you create              
      // Create S3 service client.            
      BasicAWSCredentials awsCredentials = new BasicAWSCredentials(accessKey, secretKey);
      AmazonS3Config asConfig = new AmazonS3Config()
      {
          ServiceURL = "http://irisdb.s3-ap-southeast2.amazonaws.com/",
          ServiceEndPoint = "irisdb.s3-website-ap-southeast2.amazonaws.com" //error here (cannot convert string to endpoints)
      };
      AmazonS3Client client2 = new AmazonS3Client(awsCredentials, asConfig);
      ListBucketsResponse response = client2.ListBuckets();
  

我知道我需要提供amazon . endpoint。在serviceEndPoint中存在ap- southeastern -2，但在Amazon的定义中不存在"ap- southeastern -2"。端点请帮助

AmazonS3Config asConfig = new AmazonS3Config()
{
    ServiceURL = "http://irisdb.s3-ap-southeast2.amazonaws.com/",
    RegionEndpoint = Amazon.RegionEndpoint.APSoutheast2
};
