訪問Dynamics365時發生錯誤“ Microsoft.Xrm.Sdk.dll中發生System.ServiceModel.Security.MessageSecurityException”

Question

我正在嘗試從MS Dynamics獲取數據，但是Microsoft.Xrm.Sdk.dll中出現錯誤“'System.ServiceModel.Security.MessageSecurityException”，但未在用戶代碼中處理

附加信息：從另一方收到不安全或不正確安全的故障。 有關錯誤代碼和詳細信息，請參見內部FaultException。”出現的代碼如下。

protected void Page_Load(object sender, EventArgs e)
    {
        IOrganizationService service = GetCRMService();
        QueryExpression query = new QueryExpression("account");
        query.ColumnSet.AllColumns = true;
        query.Criteria.AddCondition("name", ConditionOperator.NotEqual, "ksllls");
        EntityCollection collection = service.RetrieveMultiple(query);

        DataTable dt = new DataTable();
        dt.Columns.Add("name");
        dt.Columns.Add("accountnumber");
        foreach (Entity entity in collection.Entities)
        {
            DataRow dr = dt.NewRow();
            dr["name"] = entity.Attributes["name"].ToString();
            if (entity.Contains("accountnumber"))
            {
                dr["accountnumber"] = entity.Attributes["accountnumber"].ToString();
            }
            dt.Rows.Add(dr);
        }
        GridView1.DataSource = dt;
        GridView1.DataBind();
    }


    public IOrganizationService GetCRMService()
    {

        string UserName = "mydomain.com";
        string Password = "*****";
        ClientCredentials Credentials = new ClientCredentials();
        IOrganizationService Service;
        Credentials.UserName.UserName = UserName;
        Credentials.UserName.Password = Password;

        Credentials.Windows.ClientCredential = CredentialCache.DefaultNetworkCredentials;
        //This URI need to be updated to match the servername and organisation for the environment

        string CRMServer = ConfigurationManager.AppSettings["crmserverurl"].ToString();
        Uri OrganizationUri = new Uri(CRMServer);
        Uri HomeRealmUri = null;
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
        // OrgaizationServiceProxy  ServiceProxy

        using (OrganizationServiceProxy ServiceProxy = new OrganizationServiceProxy(OrganizationUri, null, Credentials, null))
        {
            Service = (IOrganizationService)ServiceProxy;
        }
        return Service;
    }

錯誤在EntityCollection collection = service.RetrieveMultiple（query）;行中。 誰能幫我解決

我遇到了類似的問題，並嘗試刪除並再次添加microsoft.xrm.sdk.dll。 您在代碼中提到的CRM的登錄憑據可能不同或不正確。 我之所以這樣說是因為我遇到了同樣的問題，並且發現我的登錄憑據不正確，所以我更正了憑據並且它工作正常。

謝謝，Shubham Grover
