如何在MSGRAPH .NET SDK中设置用户代理字符串

Question

我正在使用C＃中的MSGraph SDK v4.27.0读取客户电子邮件帐户。它运行良好，但一位客户坚持使用允许清单来访问电子邮件。授予对提供用户代理字符串的应用程序的访问，但是如何使用SDK调用将其包含在MSGraph标题中？
代码取自MS示例

var scopes = new[] { "User.Read","Mail.ReadWrite","Mail.ReadWrite.Shared" };

var options = new TokenCredentialOptions
            {
                AuthorityHost = AzureAuthorityHosts.AzurePublicCloud
            };

var userName = strAccount;

var password = strPWD ;


var userNamePasswordCredential = new UsernamePasswordCredential(
                userName, password, tenantId, theClientId, options);


var graphClient = new GraphServiceClient(userNamePasswordCredential, scopes);

try
{
   rootFolder = await graphClient.Me.MailFolders["msgfolderroot"]
               .Request()
               .GetAsync();
}..

Answer 1

请注意，V5的此更改

是通过标头，不再使用标题类。使用RequestConfiguration修饰符添加标题如下

var user = await graphServiceClient
.Users["{user-id}"]
.GetAsync(requestConfiguration => requestConfiguration.Headers.Add("ConsistencyLevel","eventual"));

Answer 2

最终发现了GitHubs文档的答案，尽管确实进行了一些实验，发现标题选项名称为“用户代理”
您创建一个选项列表并添加在用户代理选项中

 List<Option> theOptions = new List<Option>();
        theOptions.Add(new HeaderOption("User-Agent", "MyUserAgentName"));

，然后每个.request（）调用必须将选项作为参数

 rootFolder = await graphClient.Me.MailFolders["msgfolderroot"]
                .Request(theOptions)
                .GetAsync();
