用C＃创建目录 [英] Create a Directory in C#

问题描述

嗨



我在C＃中创建目录

Hi

I am Creating a directory in C#

if (rows_affected == true)
        {

        
           Directory.CreateDirectory(Server.MapPath(@"~/Documents/Category/")+ Category_Id);
           
        }

此代码使用Category_Id创建目录



现在我想要要创建一个子目录，我想在类别ID文件夹中创建一个目录我是如何做到这一点的 Category_Id 是不固定的。

This Code Creating a directory with Category_Id

Now I want to Create a SubDirectory , I want to create a directory in Category Id Folder How I do this and Category_Id is not fixed.

if (rows_affected == true)
        {
            Directory.CreateDirectory(Server.MapPath(@"~/Documents/Category") + category_id +  subcategory_id);
          
            Response.Redirect("~/List_SubCategory.aspx");
            Message_Label.ForeColor = System.Drawing.Color.Green;
        }

推荐答案

基本上，你需要在Category_Id和subcategory_id
目前，（假设您的Cat ID为ABC且您的子猫为DEF），您要求系统创建

Basically, you need a "\" between the "Category_Id" and the "subcategory_id"
At the moment, (assuming your Cat ID is "ABC" and your sub cat is "DEF") you are asking teh system to create

D:\Temp\ABC

然后

And then

D:\Temp\ABCDEF

何时你想要的是

When what you want is

D:\Temp\ABC\DEF

最好的方法这是使用Path.Combine：

The best way to do this is to use Path.Combine:

string path = Path.Combine(Server.MapPath(@"~/Documents/Category/"), category_id,  subcategory_id);
Directory.CreateDirectory(path)

因为这会根据需要添加和删除斜杠。

As this will add and remove slashes as necessary.
