在C＃中试图填充树视图时出现问题 [英] got a problem in C# trying to populate a treeview

问题描述

我正在尝试填充树状视图以使用C＃语言显示计算机上的所有文件夹

i尝试了许多不同的方法但没有工作

可以任何一个请帮我解决

解决方案

你好Sean，

你可以用

string [] drives = Environment.GetLogicalDrives （）从您的计算机获取所有驱动器。然后你可以使用

string [] folders = Directory.GetDirectories（path）;将所有文件夹放到相应的路径上。



您可以尝试以下代码



//

string [] driveList = Environment.GetLogicalDrives（）;

TreeNode treeNodeParent = new TreeNode（）;

TreeNode treeNodeChd = new TreeNode（） ;

foreach（字符串s在driveList中）

{

treeNodeChd = new TreeNode（）;



treeNodeChd = getDirectories（s）;

treeNodeChd.Text = s;

treeNodeParent.ChildNodes.Add（treeNodeChd）;

}

TreeView1.Nodes.Add（treeNodeParent）;



//调用每个目录中的文件夹的功能

public TreeNode getDirectories（string path）

{

string [] dirList = Directory.GetDirectories（path）;

TreeNo de treeNode = new TreeNode（）;

foreach（dirList中的字符串s）

{

TreeNode treeChildNode = new TreeNode（）;



treeChildNode = getDirectories（s）;

treeChildNode.Text = s;

treeNode.ChildNodes.Add（treeChildNode） ）;

}

返回treeNode;

}



希望它是有用..

am trying to to populate a tree view to display all folders on my computer using the C# language
i have try many different ways but none worked
can any one please help me out

解决方案

Hi Sean,
You can use
string[] drives=Environment.GetLogicalDrives() to get all the Drives from your computer. and then you can use
string[] folders = Directory.GetDirectories(path); to get all the folders to the respective Path.

U can try the following code

//
string[] driveList = Environment.GetLogicalDrives();
TreeNode treeNodeParent = new TreeNode();
TreeNode treeNodeChd = new TreeNode();
foreach(string s in driveList)
{
treeNodeChd = new TreeNode();

treeNodeChd = getDirectories(s);
treeNodeChd.Text = s;
treeNodeParent.ChildNodes.Add(treeNodeChd);
}
TreeView1.Nodes.Add(treeNodeParent);

//Function to call to get folders in each Directory
public TreeNode getDirectories(string path)
{
string[] dirList = Directory.GetDirectories(path);
TreeNode treeNode = new TreeNode();
foreach (string s in dirList)
{
TreeNode treeChildNode = new TreeNode();

treeChildNode = getDirectories(s);
treeChildNode.Text = s;
treeNode.ChildNodes.Add(treeChildNode);
}
return treeNode;
}

Hope it is helpful..
