In order to upload a file to your bucket in Amazon S3, you would need to import their AWSSDK package from your Nuget manager. Once you have done that, you can use this piece of code to get your file uploaded. Please note that you would require the awsAccessKeyId , awsSecretAccessKey and the region endpoint when you setup your AmazonS3Client object. Once you do that, you would require the name of the bucket you want to upload your file to. Please ensure that the bucket has the required access to accept files from outside source.

using Amazon.S3;
using Amazon;
using Amazon.S3.Transfer;

  using (var client = new AmazonS3Client("awsAccessKeyId", 
               "awsSecretAccessKey", RegionEndpoint.{yourregionendpoint}))
    {
      PutObjectRequest objReq = new PutObjectRequest
     {
         Key = "FolderName"+"/"+"ImageOne", //If you create folder inside bucket then you use key otherwise without key also upload data successfully.
         FilePath = "E:\\blah\\imageone.jpg",
         BucketName = "your bucket name",
         CannedACL = S3CannedACL.Private,
     };

        PutObjectResponse response = s3newClient.PutObject(objReq);
        if (response.ETag != null)
           {
            string etag = response.ETag;
            string versionID = response.VersionId;
           }
        }
    }
