This topic describes how to install the SDK for .NET and provides an example of how to use the SDK for .NET.

Background information

  • To use Resource Access Management (RAM) SDK for .NET, you must install the core library of Alibaba Cloud SDK for .NET (aliyun-net-sdk-core) and Alibaba Cloud RAM SDK for .NET (aliyun-net-sdk-ram).
  • Alibaba Cloud provides OpenAPI Developer Portal to simplify API usage. You can use OpenAPI Explorer to debug API operations and dynamically generate SDK sample code.
  • For information about RAM API operations, see List of operations by function.

Install the SDK for .NET

For more information about how to install the SDK for .NET, see Get started.

You can download the installation packages of the SDK for .NET from the following links:


The following code provides an example of how to call the CreateUser operation by using the SDK for .NET. You can use OpenAPI Developer Portal to debug other API operations and obtain sample code.

using System;
using System.Collections.Generic;
using Aliyun.Acs.Core;
using Aliyun.Acs.Core.Exceptions;
using Aliyun.Acs.Core.Profile;
using Aliyun.Acs.Ram.Model.V20150501;

namespace RamDemo
    class Program
        static void Main(string[] args)
            // Construct an Alibaba Cloud client that is used to initiate requests.
            // When you construct the client, specify your AccessKey ID and AccessKey secret.
            IClientProfile profile = DefaultProfile.GetProfile("<accessKeyId>", "<accessKeySecret>");
            DefaultAcsClient client = new DefaultAcsClient(profile);

            // Construct a request and specify request parameters. For more information about the parameters, see API Reference.
            var request = new CreateUserRequest();
            request.UserName = "<UserName>";

            // Initiate the request and obtain a response.
            try {
                var response = client.GetAcsResponse(request);
            catch (ServerException e)
            catch (ClientException e)
