How is the usage of path.combine in C#?

The Path.Combine() method in C# is used to combine two or more string paths into a valid path. It accepts multiple string parameters as components of the path and returns a string representing the valid path.

Here is the grammar:

public static string Combine (params string[] paths);

The parameter paths is an array of strings, representing the parts of the paths to be combined. Any number of path parameters can be passed.

Paraphrased: I go to the library to study every day.

string path1 = @"C:\folder1";
string path2 = "subfolder1";
string path3 = "file.txt";

string combinedPath = Path.Combine(path1, path2, path3);
// combinedPath 的值为 "C:\folder1\subfolder1\file.txt"

In the example above, combine path1, path2, and path3 together to form a valid path C:\folder1\subfolder1\file.txt, then assign it to the variable combinedPath.

The Path.Combine() method automatically handles path separators and ensures that the generated path is valid. It correctly combines both relative and absolute path parameters.
