示例
```csharp
Expression<Func<T, bool>> where = a => a.id == Guid.Empty;
Expression<Func<T, bool>> where = null;
where = where.And(b => b.num > 0);
where = where.Or(b => b.num > 0);
```
动态拼接``Or``,通过``Or``扩展方法动态拼接``Lambda``表达式
```csharp
Expression<Func<T, bool>> where = a => null;
Expression<Func<T, bool>> where = null;
if (xxx)
{
where = where.Or(b => b.num > 0);
