如何提供此代码。我想要简化的 Linq 代码

Question

我有这个代码：

dl.db.Table.First(x => x.Id == T.Id).Column1 = "a";
dl.db.Table.First(x => x.Id == T.Id).Column2 = "b"; 
dl.db.Table.First(x => x.Id == T.Id).Column3 = "c"; 
dl.db.Table.First(x => x.Id == T.Id).Column4 = "d"; 
dl.db.Table.First(x => x.Id == T.Id).Column5 = "e"; 

我想做这样的东西但我做不到

dl.db.Table.First(x => x.Id == T.Id){    
   Column1 = "a";    
   Column2 = "b";    
   Column3 = "c";      
   Column4 = "d";    
   Column5 = "e"; 
}

Answer 1

首先从表中获取元素并将其存储到变量中，然后修改该变量：

var e = dl.db.Table.First(x => x.Id == T.Id);
e.Column1 = "a";
e.Column2 = "b"; 
e.Column3 = "c"; 
e.Column4 = "d"; 
e.Column5 = "e";
