linq to object query to exclude 0

Question

我有一個Linq查詢如下。

var DataSource = from m in product 
       select new { Class = m.Class, Id = (new Make(m.Id)).ProductName}; 

我實例化一個名爲Make類以及基於Id獲取ProductName。 一些Id的是0. 有沒有辦法可以排除所有的Id是0？

Answer 1

您正在尋找的where條款：

where m.Id != 0 

Answer 2

當然，只是這樣做：

var DataSource = from m in product 
       where m.Id != 0 
       select new 
       { 
        Class = m.Class, 
        Id = (new Make(m.Id)).ProductName 
       }; 

Answer 3

var DataSource = from m in product 
       where m.Id != 0 
       select new 
       { 
        Class = m.Class, 
        Id = (new Make(m.Id)).ProductName 
       }; 

Answer 4

試試這個：

var DataSource = from m in product 
           where m.Id != 0 
           select new { Class = m.Class, Id = (new Make(m.Id)).ProductName};
