C# syntax to initialize custom class/objects through constructor params in array?
提问by BerggreenDK
I have a class with minimum 4 variables and I have made a constructor for the class so that I can initialize it with
我有一个至少有 4 个变量的类，并且我为该类创建了一个构造函数，以便我可以用
MyClass testobj = new MyClass(1234,56789,"test text", "something else", "foo");
Works fine.
工作正常。
Then I have an array of these, that I need to parse in a loop, so I would like to get some static data into this array.
然后我有一个数组，我需要在循环中解析它们，所以我想将一些静态数据放入这个数组中。
My approach was:
我的方法是：
MyClass[] testobjlist = new MyClass
{
new MyClass(1001,1234,"Text 1", "abcdefghijklm", "ding"),
new MyClass(1002,2345,"Text xx", "bla bla", "dong"),
new MyClass(1003,8653,"Text yy", "blah blah even more", "bamm!")
}
but somehow this gives me a weird error about me needing an extra } ???
但不知何故这给了我一个奇怪的错误，关于我需要一个额外的 } ???
I dunno if I should mention this, but I use it for webpages using Razor-engine 2. But I think this is an ordinary C# question?
我不知道我是否应该提及这一点，但我将它用于使用 Razor-engine 2 的网页。但我认为这是一个普通的 C# 问题？
My workaround is currently to initialize the array with a size, then adding the elements one by one through index, but I would rather prefere the above solution as I might have to move the items up and down in order when testing and I have a lot more than 3 in the real data.
我的解决方法目前是用一个大小初始化数组，然后通过索引一个一个地添加元素，但我更喜欢上面的解决方案，因为我可能需要在测试时按顺序上下移动项目，而且我有很多实际数据中超过3个。
Wondering what I am missing in the above code...?
想知道我在上面的代码中缺少什么......？

Try adding square brackets after new MyClass and a semi-colon at the end
尝试在 new MyClass 之后添加方括号并在末尾添加分号
MyClass[] testobjlist = new MyClass[]
{
new MyClass(1001,1234,"Text 1", "abcdefghijklm", "ding"),
new MyClass(1002,2345,"Text xx", "bla bla", "dong"),
new MyClass(1003,8653,"Text yy", "blah blah even more", "bamm!")
};

You want:
你要：
MyClass[] testobjlist = new MyClass[] { ... }
You were missing the brackets toward the end.
你在最后错过了括号。

Shorthand for the win:
胜利的简写：
var myClassList = new[]
{
new MyClass(1001,1234,"Text 1", "abcdefghijklm", "ding"),
new MyClass(1002,2345,"Text xx", "bla bla", "dong")
};

MyClass[] testobjlist =
{
new MyClass(1001,1234,"Text 1", "abcdefghijklm", "ding"),
new MyClass(1002,2345,"Text xx", "bla bla", "dong"),
new MyClass(1003,8653,"Text yy", "blah blah even more", "bamm!")
};

this will also work without a need to create a constructure
这也无需创建结构即可工作
new MyClass [] { new MyClass { Field1 = "aa", Field2 = 1 } }
回答by Hasala Senevirathne
MyClass[] testobjlist = new MyClass[noOfObjects];
for(int i = 0; i < testobjlist.Length; i++) { testobjlist[i] = new MyClass(); }
回答by Hari Lakkakula
You can use below code for the array:
您可以对数组使用以下代码：
additionalusers[] __adiitonaluser =
{
new additionalusers()
};
__adiitonaluser[0].Email = Userpersonal.Email;
