Question

当我使用c＃代码在sharepoint的指定目录中创建子目录时遇到了异常。

异常消息： Microsoft.SharePoint.Client.ServerUnauthorizedAccessException：访问被拒绝。您没有执行此操作或访问此资源的权限。

有人可以帮助我吗？谢谢！

已对您的代码进行了测试，效果很好。确保用户名/密码正确。

class Program
    {

        const string user = "user@teanat.onmicrosoft.com";
        const string password = "password";
        public static void Upload()

                SecureString pass = new SecureString();
                foreach (char ch in password)
                {
                    pass.AppendChar(ch);
                }
                clientContext.Credentials = new SharePointOnlineCredentials(user, pass);
                Web web = clientContext.Web;
                clientContext.Load(web);
                clientContext.ExecuteQuery();

            return curFolder;
