這篇文章是我在之前那篇文章上的深入，可以獲取到列表後，在右邊將圖片顯示出來，並添加了上傳功能，好啦，不多說了，代碼如下
首先是winform的佈局代碼
namespace TreeviewTest
{
partial class Form1
{
/// <summary>
/// 必需的設計器變量。
/// </summary>
private System.ComponentModel.IContainer components = null;
/// <summary>
/// 清理所有正在使用的資源。
/// </summary>
/// <param name="disposing">如果應釋放託管資源，爲 true；否則爲 false。</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
#region Windows 窗體設計器生成的代碼
/// <summary>
/// 設計器支持所需的方法 - 不要
/// 使用代碼編輯器修改此方法的內容。
/// </summary>
private void InitializeComponent()
{
this.treeView1 = new System.Windows.Forms.TreeView();
this.panel1 = new System.Windows.Forms.Panel();
this.button1 = new System.Windows.Forms.Button();
this.button2 = new System.Windows.Forms.Button();
this.button3 = new System.Windows.Forms.Button();
this.SuspendLayout();
//

//
this.treeView1.Location = new System.Drawing.Point(13, 13);
this.treeView1.Name = "treeView1";
this.treeView1.Size = new System.Drawing.Size(217, 415);

this.panel1.BorderStyle = System.Windows.Forms.BorderStyle.FixedSingle;
this.panel1.Location = new System.Drawing.Point(237, 42);
this.panel1.Name = "panel1";
this.panel1.Size = new System.Drawing.Size(559, 386);
this.panel1.TabIndex = 1;
//
// button1
//
this.button1.Location = new System.Drawing.Point(237, 13);
this.button1.Name = "button1";
this.button1.Size = new System.Drawing.Size(75, 23);
this.button1.TabIndex = 2;
this.button1.Text = "全選";

this.button1.Click += new System.EventHandler(this.button1_Click);

this.button2.Size = new System.Drawing.Size(75, 23);
this.button2.TabIndex = 3;

//

//
this.button3.Location = new System.Drawing.Point(721, 12);
this.button3.Name = "button3";
this.button3.Size = new System.Drawing.Size(75, 23);
this.button3.TabIndex = 4;
this.button3.Text = "上傳";
this.button3.UseVisualStyleBackColor = true;
this.button3.Click += new System.EventHandler(this.button3_Click);
//

//
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(808, 440);
this.Controls.Add(this.button3);
this.Controls.Add(this.button2);
this.Controls.Add(this.button1);
this.Controls.Add(this.panel1);
this.Controls.Add(this.treeView1);
this.Name = "Form1";
this.Text = "Form1";
this.ResumeLayout(false);
}
#endregion
private System.Windows.Forms.TreeView treeView1;
private System.Windows.Forms.Panel panel1;

接下是後臺功能實現的代碼

this.treeView1.ImageList = imglist;
DriveInfo[] dr = DriveInfo.GetDrives();
string driveName = "";
foreach (DriveInfo d in dr)
{

try

foreach (string s in allDirectory)

這樣就是實現了本地圖片批量上傳的功能，大家再結合那篇c# active控件開發的技術，就能完成圖片上傳控件了
