'Unexpected error occurred Platform' - 这可能是由于错误地查询了一个选择列表吗？

Question

我正在尝试 return 来自自定义实体的 'team members' 列表，其中它们的角色与特定值列表相匹配。我试图匹配的属性是一个选择列表，我想知道这是否导致了我的错误。这是我的代码：

public static BusinessEntityCollection GetTeamMembers(string BU, string[] roles)
{
    BusinessEntityCollection TeamMembers = new BusinessEntityCollection();

    ColumnSet cols = new ColumnSet();
    cols.Attributes = new string[] { "new_teamid", "new_id", "new_name", "ownerid", "new_rolepicklist" };

    QueryExpression query = new QueryExpression();
    query.ColumnSet = cols;
    query.EntityName = EntityName.new_team.ToString();

    List<ConditionExpression> ceList = new List<ConditionExpression>();

    foreach (string role in roles)
    {
        //I suspect it this block is where the problem occurs as 'new_rolepicklist' is a picklist, and 'role' will be something like 'Manager' (a picklist value).
        ConditionExpression ce2 = new ConditionExpression();
        ce2.AttributeName = "new_rolepicklist";
        ce2.Operator = ConditionOperator.Like;
        ce2.Values = new string[]{role};

        ceList.Add(ce2);
    }

    FilterExpression filter = new FilterExpression();
    filter.Conditions = ceList.ToArray();
    filter.FilterOperator = LogicalOperator.Or;
    query.Criteria = filter;

    try
    {
        using (crmService)
        {
            TeamMembers = crmService.RetrieveMultiple(query); //ERROR
        }
    }
    catch (SoapException se)
    {
        throw new Exception("Error occurred retrieving Team Members for " + BU + ". " + se.Detail.InnerXml);
    }
    catch (Exception ex)
    {
        throw new Exception("Error occurred retrieving Team Members for " + BU + ". " + ex.Message);            
    }

    return TeamMembers;
}

首先，是否有任何明显可能导致此错误的原因？其次，如果是选择列表部分，我该如何解决？如何查询作为具有选项列表值的选项列表的属性？

更新

按照 Alex 的正确答案，为了完成，我编辑了我的方法以获取 int[] 角色以及 foreach（角色中的 int 角色）和 ce2.Values = new object[] {role}（一个 int此处不允许 [])。

当涉及到比较时，您的代码令人窒息：选项列表值的类型为 int，但您正在提供 strings。一旦类型匹配，它应该可以工作。
