c# - 如何在早期绑定(bind)的状态代码上为 QueryExpression 创建 ConditionExpression？

Question

在后期绑定(bind)中，我会使用类似这样的东西来添加仅获取事件记录的条件。

new ConditionExpression
{
  AttributeName = "statecode",
  Operator = ConditionOperator.NotEqual,
  Values = { SomeClass.Active }
}

但是我该如何在后期绑定(bind)中表达呢？

另外，为什么 MS demand to cast it to String而不是int？

When you create a condition that compares an attribute value to an enumeration, such as a state code, you must use the ToString method to convert the value to a string.

Answer 1

有点像

ConditionExpression condition1 = new Microsoft.Xrm.Sdk.Query.ConditionExpression
{
    AttributeName = "statecode",
    Operator = ConditionOperator.Equal,
    Values = { "Active" } //or SomeEnum.Active.ToString() if you want use good practice
};

应该可以正常工作。

编辑:另一种选择是将枚举转换为 int:Values = {(int)SomeEnum.Active}
