Add Properties to string
问题
这是您提供的代码的翻译部分：
它关闭了我的原始问题。对C#相当新，我想知道是否有一种方法可以实现以下操作：
string joint = "Press Joint" || "ProPress";
我是否可以使用switch语句来实现这一点？即将字符串设置为空，并以编程方式提取一个值，然后根据该值切换情况？我已经创建了一个更新程序实用程序，用于检查Revit中的模型，以强制执行最小管道长度标准。代码相当长，但希望我提取出来的内容有意义。

变量pressJoint的字符串值可以在"Press Joint"、"ProPress"和"PressFit"之间变化。
英文:
It closed my original question. Fairly new to c# & I'm wondering if there is a way to do the following:
string joint = "Press Joint" || "ProPress";
Would I achieve this using a switch statement? I.e. set the string to be empty & programmatically pull a value & switch the case depending on the value? I've created an updater utility to check the models in Revit to enforce minimum pipe length standards. The code is pretty lengthy but hopefully what I pulled out makes sense.

The string value pressJoint can vary with what is being checked between "Press Joint", "ProPress", & "PressFit".

No. A string is one value. If you want to test whether a string is something or something else - or one of some set of options, then:
- for constant strings, you can use
if (value is "abc" or "def") {...} - otherwise, create some kind of collection (perhaps a
HashSet<string>) and useif (options.Contains(value)) {...}

你似乎想要能够在同一个变量中存储两个值。对此，你不需要使用字符串。我建议你使用一个List<string>()
List<string> joints = new List<string>();
然后添加到列表中，
joints.Add("Press Joint");
joints.Add("ProPress");
要检查是否存在匹配，
if (joints.Contains(brazed))
{
//进行一些操作
}
希望这能帮到你。
英文:
You appear to want to be able to store two values in the same variable. You don't want a string for that. I would suggest you use a List<string>()
List<string> joints = new List<string>();
Then to add to the list,
joints.Add("Press Joint");
joints.Add("ProPress");
To check for a match,
if (joints.Contains(brazed)
{
//do something
}
I hope this helps.
