圖片上傳/文件從ASP Web應用程序到SharePoint在線

Question

新手開發這裏的問題，我很感激:-)一些援助

我正在開發一個ASP Web應用程序（一個簡單的公告牌，這使得用戶創建買賣廣告）。我所有的數據都是從MSSQL數據庫中存儲/檢索的。但是，我希望使用SharePoint Online庫存儲/檢索廣告的圖像。

我在第一個關卡上掙扎，這是將圖像上傳到圖書館。我已經調試和調試了一些，但我仍然碰到一堵磚牆。經過幾個小時的嘗試後，我現在有了下面的代碼，儘管圖像從未出現在目標庫中，但不再返回任何錯誤。

鑑於以上所述，我衷心感謝任何專家的幫助！

當按下「創建廣告」按鈕時，將觸發以下代碼。

string currentUserName = 
System.DirectoryServices.AccountManagement.UserPrincipal.Current.DisplayName; 

SqlConnection conn2; 
SqlCommand comm2; 
SqlDataReader reader; 

string connectionString2 = 

ConfigurationManager.ConnectionStrings["CCString"].ConnectionString; 
conn2 = new SqlConnection(connectionString2); 
comm2 = new SqlCommand("SELECT TOP 1 * FROM Threads WHERE ([AdvertiserName] = '" + currentUserName + "') ORDER BY PostCreationDateTime DESC", conn2); 

conn2.Open(); 
reader = comm2.ExecuteReader(); 
reader.Read(); 

Guid imageID; 
string imageIDConfirmed = ""; 
string fileExtension = ""; 

if (reader["UniqueImageID"].GetType().Name != "DBNull") 
{ 
imageID = (Guid)reader["UniqueImageID"]; 
imageIDConfirmed = imageID.ToString().Replace(":", "-"); 
string myFile = jpgFileUpload.FileName; 
fileExtension = myFile.Substring(myFile.Length - 4, 4); 
} 

reader.Close(); 
conn2.Close(); 

string username = "username@emailaddress.com"; 
string password = "password"; 

System.Security.SecureString securePass = new 
System.Security.SecureString(); 
foreach (char ch in password.ToCharArray()) securePass.AppendChar(ch); 
SharePointOnlineCredentials credentials = new 
SharePointOnlineCredentials(username, securePass); 
using (ClientContext client = new 
ClientContext("https://company.sharepoint.com/sites/SiteName/")) 
{ 
var formLib = client.Web.Lists.GetByTitle("Documents"); 
client.Credentials = credentials; 
client.Load(formLib.RootFolder); 
client.ExecuteQuery(); 

string fileName = @"C:\Temp\" + jpgFileUpload.FileName; 
jpgFileUpload.SaveAs(fileName); 

var fileUrl = ""; 

int fileLen; 
fileLen = jpgFileUpload.PostedFile.ContentLength; 
byte[] input = new byte[fileLen - 1]; 
input = jpgFileUpload.FileBytes; 

UploadDocument(@"https://company.sharepoint.com/sites/SiteName/", "Documents", "https://company.sharepoint.com/sites/SiteName/Shared%20Documents/", "testDocument", input); 

using (var fs = new FileStream(fileName, FileMode.Open)) 
{ 
var fi = new FileInfo(imageIDConfirmed + fileExtension); 
fileUrl = String.Format("{0}/{1}", formLib.RootFolder.ServerRelativeUrl, fi.Name); 
Microsoft.SharePoint.Client.File.SaveBinaryDirect(client, fileUrl, fs, true); 
client.ExecuteQuery(); 
} 

var libFields = formLib.Fields; 
client.Load(libFields); 
client.ExecuteQuery(); 

Microsoft.SharePoint.Client.File newFile = 
client.Web.GetFileByServerRelativeUrl(fileUrl); 
Microsoft.SharePoint.Client.ListItem item = newFile.ListItemAllFields; 
item["Title"] = "Any Title"; 
item["File Name"] = "Any File Name"; 
item.Update(); 
client.Credentials = credentials; 
client.ExecuteQuery();

，因此不再返回任何錯誤雖然圖像不會出現在目標庫

是否有可能這些文件是否存在，但在一些未選中電狀態？

如果沒有檢入版本的文件，這可能表示需要在代碼中提供簽入邏輯，或者可能存在必填字段的問題。
