Saving a file and automatically create directories
提问by leora
I am concatenating a number of variables and I want to save that string as a file path.
我连接了许多变量，我想将该字符串保存为文件路径。
Is there a way it will automatically create all appropriate directories if they don't exist without having to check "if exists" on each one
有没有一种方法，如果它们不存在，它会自动创建所有适当的目录，而不必检查每个目录的“是否存在”
For example.
例如。
"C:\" + a + "\" + b+ "\" + d + "\" + d + ".txt"
采纳答案by Jon Skeet
Use new FileInfo(path).Directory.Create().
使用new FileInfo(path).Directory.Create().
(This creates anything in the hierarchy that's required. If the directory already exists it does nothing.)
（这会在层次结构中创建所需的任何内容。如果目录已经存在，则它什么都不做。）
