[英]Linq does not work with MonoDevelop/Mono last version on Mac OSX 10.6.4
我正在尝试执行一个简单的测试代码:
using System;
using System.IO;
using System.Linq;
using System.Collections.Generic;
namespace TestMono
{
public class TesterManager
{
public TesterManager ()
{
Console.WriteLine("Test");
Path.GetTempPath();
foreach (var i in new int[] { 1, 2, 3, 4, 5}.Where(n => n % 2 == 0))
{
Console.WriteLine(i);
}
List<string> ar= new List<string>();
ar.Add("1"); ar.Add("2");
var lb = ar.Where(n => n=="2");
}
}
}
编译该代码我有两个错误:
Esecuzione compilazione principale...

我在项目属性中设置了Mono / .NET 3.5,并且具有Mono和MonoDevelop的最新版本。 我不明白这是怎么回事!
您可能需要添加对“ System.Core.dll”的引用才能访问“ System.Linq”命名空间。
这个让我挠了一下头,我已经习惯于Resharper引入我的参考文献。
您是否添加了对System.Linq.dll的引用(或在Mono中称为的引用)?
(我可以发誓VS问同样的问题; P)
