小编Cha*_*win的帖子

svn在命令行中输入时,我得到响应:

$ svn
svn: E200019: Version mismatch in 'svn_diff' (expecting equality): found 1.9.6, expected 1.9.4
svn: E200019: Version mismatch in 'svn_delta' (expecting equality): found 1.9.6, expected 1.9.4
svn: E200019: Version mismatch in 'svn_ra' (expecting equality): found 1.9.6, expected 1.9.4

svn: E200019: Version mismatch in 'svn_subr' (expecting equality): found 1.9.6, expected 1.9.4

我安装了最新版本的TortoiseSVN,并完全重启了计算机.

我假设错误是与仍在计算机上安装的旧版本的subversion有关,但是我认为在安装最新版本的Tortoise时这将被删除.

class Test<string, T> : System.Collections.Concurrent.ConcurrentDictionary<string, T>

上面的代码返回两个错误:

• CS1001标识符

• CS1003语法错误,','预期

但是,大写string内部测试不会产生任何错误.

class Test<String, T> : System.Collections.Concurrent.ConcurrentDictionary<string, T>

任何人都可以解释为什么编译器在string小写时会产生这些错误,但不是大写的时候？

如何将a的值写入hashset控制台？我不想使用foreach循环.

HashSet<string> hashSet=new HashSet<string>();
hashSet.Add("Employee");
hashSet.Add("Employee1");
Console.WriteLine(hashSet.Select(x=>x));

产量

System.Linq.Enumerable

预期产出

员工,Employee1
