如何设置多个自定义字段?-Microsoft Project Server

我是Project Server开发的新手，想知道需要对以下代码进行哪些修改。我必须让它一次更新多个自定义字段。在我想要开始更新多个定制字段之前，我已经做好了所有工作。我已经看了很多教程，还没有找到一个适用于这个问题的解决方案。我目前编写的程序只更新了第一个ForEach cfValueWOD自定义字段。如果多个字段已经有值，我可以让代码更新它们，但对于我的项目，这些自定义字段可以有初始值，也可以没有值启动。在这两种情况下，我都需要将值写入这些字段。我需要很快完成一个正在工作的项目，我不知所措。我们将非常感谢你的帮助。我当前的代码如下：

{
    static void WriteCustomFields()
    {
        //Guids for custom fields to update - Test
        string cfNameWOD = "WO Description"; //Test WO Description custom field
        string cfValueWOD = "xxxx5WODes";
        Guid cfIdWOD = new Guid("{8071365c-1375-46a1-9424-cd79f3c2b0db}");
        string cfNameWG = "Work Group"; //Test Work Group custom field
        string cfValueWG = "xxxx5Group";
        Guid cfIdWG = new Guid("{f75c6cfb-b7cb-4d35-8b04-60efb12fcd39}");                
        //projects into a dataset
        ProjectDataSet projectList = projectSvc.ReadProjectList();
        //read project data
        Guid myProjectUid = new Guid("{c96bd7ea-e9d2-47ed-8819-02e4653e92a7}");
        ProjectDataSet myProject = projectSvc.ReadProject(myProjectUid, DataStoreEnum.WorkingStore);
        //indicate the custom field has been found
       bool customFieldFound = false;
        //iterate over fields and update them to the table for WO Status
        foreach (ProjectDataSet.ProjectCustomFieldsRow cfRow in myProject.ProjectCustomFields)
        {
            //if field exists update it
            if (cfRow.MD_PROP_UID == cfIdWOD)
            {
                //update the value
                cfRow.TEXT_VALUE = cfValueWOD;
                customFieldFound = true;
            }
        }
        //check if the custom field has been found
        if (!customFieldFound)
        {
            //create a new row
            ProjectDataSet.ProjectCustomFieldsRow cfRowWOD =
                myProject.ProjectCustomFields.NewProjectCustomFieldsRow();
            //Sets all values to NUll to begin
            cfRowWOD.SetDATE_VALUENull();
            cfRowWOD.SetTEXT_VALUENull();
            //General parameters
            cfRowWOD.MD_PROP_UID = cfIdWOD; //custom field ID
            cfRowWOD.CUSTOM_FIELD_UID = Guid.NewGuid();
            cfRowWOD.PROJ_UID = myProjectUid; //current project ID
            //add value
            cfRowWOD.FIELD_TYPE_ENUM = 21;
            cfRowWOD.TEXT_VALUE = Convert.ToString(cfValueWOD); //test value
            //add the row to the data set
            myProject.ProjectCustomFields.AddProjectCustomFieldsRow(cfRowWOD);
