C# 通过指定公用文件夹的路径名搜索其文件夹
是否可以通过使用Exchange Web Service(EWS)托管Api提供文件夹的路径来搜索公用文件夹中的所有文件夹和文件夹?您只能在文件夹内搜索,在EWS上搜索一级,以便: PublicFoldersRoot\subjectA\sectionB\partC\ 我会搜索“subjectA”文件夹,一旦我有了这个文件夹ID,我就会搜索“sectionB”文件夹等等,直到我找到我需要的东西 方法C# 通过指定公用文件夹的路径名搜索其文件夹,c#,web-services,api,exchange-server,managed,C#,Web Services,Api,Exchange Server,Managed,是否可以通过使用Exchange Web Service(EWS)托管Api提供文件夹的路径来搜索公用文件夹中的所有文件夹和文件夹?您只能在文件夹内搜索,在EWS上搜索一级,以便: PublicFoldersRoot\subjectA\sectionB\partC\ 我会搜索“subjectA”文件夹,一旦我有了这个文件夹ID,我就会搜索“sectionB”文件夹等等,直到我找到我需要的东西 方法GetPublicFolderByPath获取路径“subjectA\sectonB\partC\”
GetPublicFolderByPath
获取路径“subjectA\sectonB\partC\”并将路径拆分为文件夹名称数组,然后递归查找每个文件夹
public Folder GetPublicFolderByPath(ExchangeService service, String ewsFolderPath)
{
String[] folders = ewsFolderPath.Split('\');
Folder parentFolderId = null;
Folder actualFolder = null;
for (int i = 0; i < folders.Count(); i++)
{
if (0 == i)
{
parentFolderId = GetTopLevelFolder(service, folders[i]);// for first first loop public folder root is the parent
actualFolder = parentFolderId; //in case folders[] is only one long
}
else
{
actualFolder = GetFolder(service, parentFolderId.Id, folders[i]);
parentFolderId = actualFolder;
}
}
return actualFolder;
}
GetFolder
方法获取父文件夹ID,并在所有子文件夹中搜索名称上的匹配项,然后返回您请求的子文件夹ID
private Folder GetFolder(ExchangeService service, FolderId ParentFolderId, String folderName)
{
FolderView folderView = new FolderView(int.MaxValue);
FindFoldersResults findFolderResults = service.FindFolders(ParentFolderId, folderView);
foreach (Folder folder in findFolderResults)
{
if (folderName.Equals(folder.DisplayName, StringComparison.InvariantCultureIgnoreCase))
{
return folder;
}
}
throw new Exception("Folder not found: " + folderName);
}
请注意,我使用的是Microsoft.Exchange.WebServices托管API dll,与https://yourexchangeserver/ews/services.wsdl
。要从路径中获取文件夹,请创建ExchangeService对象,然后写入:GetPublicFolderByPath(服务,“subjectA\sectionB\partC\”)
如果这对你有帮助,请投票:)这是一个基于@ono2012答案的包装
