英文:
Visual Studio: How to get name before - of a file
问题
如何获取文件名中“-”之前的部分并将结果存入变量？
例如，文件名：test.adress-12.txt
但我只想要test.adresss
我已经尝试过搜索，但找不到任何信息，只有关于如何在Visual Code中查找和替换内容的信息。
英文:
How do I get the part before the - in the filename and put the outcome in a variable?
For example a filename: test.adress-12.txt
But I only want test.adresss
I have tried searching but couldn't find anything, only things how I can find and replace something within Visual Code itself.

C#
string fileName = "test.adress-12.txt";
string[] results = fileName.Split('-');
string result = results[0];
VB
Dim fileName As String = "test.adress-12.txt"
Dim results As String() = fileName.Split("-"c)
Dim result As String = results(0)
英文:
If you always know there will be a single - and you are using C#, then you can use string.Split('-') and take the 0th element.
C#
string fileName = "test.adress-12.txt";
string[] results = fileName.Split('-');
string result = results[0];
Here is the VB documentation for Strings.Split and here is an example of the same code in the C# example converted to VB.
VB
Dim fileName As String = "test.adress-12.txt"
Dim results As String() = fileName.Split("-"c)
Dim result As String = results(0)
