第一步，啟用Drive API

首先，申請Dropbox的帳號；其次，在Dropbox for Developers上獲得開發所需的App Key和App Sercet。

1、登入Dropbox for Developers網站；2、點擊App Console選項，選擇Create app；3、點擊Send email for verification；4、通過電子郵件驗證；5、在Create a new Dropbox Platform app上，選擇Dropbox API app；6、填寫資訊並Create app，就將獲得App key和App secret。

第二步，安裝Dropbox Client Library

安裝一個NuGet包（Dropnet）。如VS2012選擇Tools項，再選NuGet Package Manager，接著Package Manager Console。在PM>中填寫Install-Package dropnet -Pre。

第三步，編程

(_dropNetClient = new DropNetClient(tbxAppKey.Text, tbxAppSecret.Text));25             }26             set27             {28                 _dropNetClient = value;29             }30         }31         #endregion32 33         public Form1()34         {35             InitializeComponent();36         }37 38         private void btnLogin_Click(object sender, EventArgs e)39         {40             var callbackUrl = "https://www.dropbox.com/1/oauth/authorize";41             var cancelCallbackUrl = "https://www.dropbox.com/home";42             var size = new Size(1024, 600);43 44             if (DoOAuth(callbackUrl, cancelCallbackUrl, size) == DialogResult.OK)45             {46                 var accessToken = m_DropNetClient.GetAccessToken();47             }48         }49 50         private DialogResult DoOAuth(string callbackUrl, string cancelCallbackUrl, System.Drawing.Size size)51         {52             using (var dialog = new Form())53             {54                 var browesr = new WebBrowser()55                 {56                     Dock = DockStyle.Fill57                 };58 59                 m_DropNetClient.GetToken();60                 var authUrl = m_DropNetClient.BuildAuthorizeUrl();61                 browesr.Navigated += (s, ex) =>62                 {63                     var url = ex.Url.ToString();64                     if (url.Equals(callbackUrl))65                     {66                         dialog.DialogResult = DialogResult.OK;67                     }68                     else if (url.Equals(cancelCallbackUrl))69                     {70                         dialog.DialogResult = DialogResult.Cancel;71                     }72                 };73                 browesr.Navigate(authUrl);74 75                 dialog.Size = size;76                 dialog.Controls.Add(browesr);77 78                 return dialog.ShowDialog();79             }80         }81 82         private void tbxAppKey_TextChanged(object sender, EventArgs e)83         {84             m_DropNetClient = null;85         }86 87         private void tbxAppSecret_TextChanged(object sender, EventArgs e)88         {89             m_DropNetClient = null;90         }91     }92 }
