LINQ to Entities不支持LINQ表达式节点类型'NewArrayBounds' [英] The LINQ expression node type 'NewArrayBounds' is not supported in LINQ to Entities
本文介绍了LINQ to Entities不支持LINQ表达式节点类型'NewArrayBounds'的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
select new ProviderMeta
{
LoginId = user.LoginId,
AgencyId = user.AgencyId,
Application = user.Application,
UserId = user.UserId,
Name = agencySnapshot.Name,
Roles = new int[0],
Cluster = app.ClusterId ?? 0,
Created = app.Created,
TitleType = user.TitleType,
Feature = (foundFeature == null ? 0 : foundFeature.Feature)
}).ToList();
在这里,角色"是一个整数数组,但不允许我分配一个空数组 与零. 帮助将不胜感激.
Here, Roles is an integer array but it is not letting me assign an empty array with zero. Help would be appreciated.
推荐答案
在您的类的空构造函数中初始化数组:
Initialize the array in an empty constructor of your class:
public class ProviderMeta
{
//...
public ProviderMeta()
{
Roles = new int[]{0};
}
}
并将其从投影中删除
select new ProviderMeta
{
LoginId = user.LoginId,
AgencyId = user.AgencyId,
Application = user.Application,
UserId = user.UserId,
Name = agencySnapshot.Name,
//Roles = new int[0], remove this line
Cluster = app.ClusterId ?? 0,
Created = app.Created,
TitleType = user.TitleType,
Feature = (foundFeature == null ? 0 : foundFeature.Feature)
}).ToList();
