我很遗憾地问这个基本问题,
var filePath = (from Component comp1 in componentContainer where comp1.ComponentName == fileName select comp1.FilePath);
我想将输出转换为字符串。
我试过这些东西:
string filePath = (from Component comp1 in componentContainer where comp1.ComponentName == fileName select comp1.FilePath).ToString();
和
var filePath = (from Component comp1 in componentContainer where comp1.ComponentName == fileName select comp1.FilePath);
string filePathInString = filePath.ToString();
两次我都收到错误:
Linq.Internals.UnoptimizedQuery<string>
请帮帮我
我该如何解决这个问题?

尝试将查询更改为
string filePath = (from Component comp1 in componentContainer where comp1.ComponentName == fileName select comp1.FilePath).FirstOrDefault().ToString();
答案 1 :(得分:1)
string filePath=componentContainer.Single(x=>x.ComponentName==fileName).FilePath;
