在Select Distinct LINQ Expression中修改查询。

问题描述:

嗨团队,



很高兴见到你们。我在LINQ Expression中编写了查询。

我想在Select distinct LINQ表达式中修改该查询,是否可能。请指导ME。查询如下:



Hi Team,

Nice to see you all. I have written the query in LINQ Expression.
I want to modify that query in Select distinct LINQ expression,is it possible .please Guide ME.The Query is as follows:

string[] matchID = zteBbhRecords.Cast<IZteBbh>().Select(zteBbh => (zteBbh.CombinedMaster as ICombinedMaster).CellId.ToString()).GroupBy(item => item).Where(items => items.Count() > 1).Select(item => item.Key).ToArray();

因此,使用Distinct()。ToArray(),我们可以轻松获取不同的值并将它们转换为数组。

So, using Distinct().ToArray(), we can easily get the distinct values and convert them to array.
string[] matchID = zteBbhRecords.Cast<IZteBbh>()
         .Select(zteBbh => (zteBbh.CombinedMaster as ICombinedMaster)
             .CellId.ToString()).GroupBy(item => item)
             .Where(items => items.Count() > 1)
             .Select(item => item.Key).Distinct().ToArray();
