扬州阿里云代理商：asp.net 存储公用类

扬州阿里云代理商可以使用以下代码来创建一个存储公用类，用于处理文件的上传、下载、删除等操作：

using Aliyun.OSS; // 引入阿里云 OSS 的命名空间

public class OSSHelper
{
    private static string endpoint = "你的 OSS Endpoint";
    private static string accessKeyId = "你的 AccessKeyId";
    private static string accessKeySecret = "你的 AccessKeySecret";
    private static string bucketName = "你的 Bucket Name";

    private static OssClient ossClient;

    static OSSHelper()
    {
        ossClient = new OssClient(endpoint, accessKeyId, accessKeySecret);
    }

    // 上传文件
    public static bool UploadFile(string fileName, string filePath)
    {
        try
        {
            ossClient.PutObject(bucketName, fileName, filePath);
            return true;
        }
        catch (OssException ex)
        {
            Console.WriteLine("Failed to upload file. Error: {0}", ex.ErrorCode);
            return false;
        }
    }

    // 下载文件
    public static bool DownloadFile(string fileName, string savePath)
    {
        try
        {
            ossClient.GetObject(bucketName, fileName, savePath);
            return true;
        }
        catch (OssException ex)
        {
            Console.WriteLine("Failed to download file. Error: {0}", ex.ErrorCode);
            return false;
        }
    }

    // 删除文件
    public static bool DeleteFile(string fileName)
    {
        try
        {
            ossClient.DeleteObject(bucketName, fileName);
            return true;
        }
        catch (OssException ex)
        {
            Console.WriteLine("Failed to delete file. Error: {0}", ex.ErrorCode);
            return false;
        }
    }
}

在使用这个存储公用类之前，需要先通过 NuGet 安装 Aliyun.OSS 包，并替换代码中的 endpoint、accessKeyId、accessKeySecret 和 bucketName 为自己的阿里云 OSS 配置信息。然后可以使用该类的 UploadFile、DownloadFile 和 DeleteFile 方法来对文件进行操作。

在扬州，作为阿里云代理商，您可以使用ASP.NET来创建一个存储公用类，以便方便地处理与阿里云存储服务的交互。以下是一个简单的示例代码：

using Aliyun.OSS;
using System;
using System.IO;

public class AliyunStorage
{
    private static string accessKeyId = "your_access_key_id";
    private static string accessKeySecret = "your_access_key_secret";
    private static string endpoint = "http://oss-cn-hangzhou.aliyuncs.com";

    public static void UploadFile(string bucketName, string objectName, string filePath)
    {
        var client = new OssClient(endpoint, accessKeyId, accessKeySecret);
        try
        {
            client.PutObject(bucketName, objectName, filePath);
            Console.WriteLine("File uploaded successfully!");
        }
        catch (Exception ex)
        {
            Console.WriteLine("Error uploading file: " + ex.Message);
        }
    }

    public static void DownloadFile(string bucketName, string objectName, string savePath)
    {
        var client = new OssClient(endpoint, accessKeyId, accessKeySecret);
        try
        {
            client.GetObject(bucketName, objectName, savePath);
            Console.WriteLine("File downloaded successfully!");
        }
        catch (Exception ex)
        {
            Console.WriteLine("Error downloading file: " + ex.Message);
        }
    }

    public static void DeleteFile(string bucketName, string objectName)
    {
        var client = new OssClient(endpoint, accessKeyId, accessKeySecret);
        try
        {
            client.DeleteObject(bucketName, objectName);
            Console.WriteLine("File deleted successfully!");
        }
        catch (Exception ex)
        {
            Console.WriteLine("Error deleting file: " + ex.Message);
        }
    }
}

您可以根据需要进一步扩展此类，并添加其他方法以处理与阿里云存储服务的不同操作。使用此类，您可以轻松地上传、下载和删除文件。希望这可以帮助您在康复过程中更好地使用ASP.NET与阿里云存储服务进行交互。
