c# - Using Two GetDirectories and adding them together,

Question

How can I use two of the following Get Directories? I need to add them into one int, but when I use the following code I just get the same numbers.

var directoryInfo = new System.IO.DirectoryInfo(@"c:\test\");
int directoryCount = directoryInfo.GetDirectories().Length;

var directoryInfo2 = new System.IO.DirectoryInfo(@"c:\test2\");
int directoryCount2 = directoryInfo.GetDirectories().Length;

int directoryCountMain = directoryCount + directoryCount2;

Answer 1

您2在directoryCount2初始化声明中丢失了。

您使用directoryInfo.GetDirectories().Length了两次，而不是directoryInfo2在设置时使用 object directoryCount2。

var directoryInfo2 = new System.IO.DirectoryInfo(@"c:\test2\");
int directoryCount2 = directoryInfo2.GetDirectories().Length;
