使用c#在sharepoint 2007中访问列表

Question

我想从sharepoint 2007中的几个不同的客户列表中编译数据

它是一个托管的sharepoint站点,所以我无法访问机器后端.

是否有使用c#访问sharepoint站点的示例代码？

这是我到目前为止的代码(我收到错误无法连接到Sharepoint网站''.稍后再试.)

    DataSet dt = new DataSet();
    string query = "SELECT * FROM list";
    string site = "http://sp.markonsolutions.com/Lists/Security/";
    string list = "35E70EO4-6072-4T55-B741-4B75D5F3E397"; //security db
    string myConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;WSS;IMEX=2;RetrieveIds=Yes; DATABASE="+site+";LIST={"+list+"};";
    OleDbConnection myConnection = new OleDbConnection();
    myConnection.ConnectionString = myConnectionString;
    OleDbCommand myAccessCommand = new OleDbCommand(query,myConnection);
    OleDbDataAdapter myDataAdapter = new OleDbDataAdapter(myAccessCommand);
    myConnection.Open();



          myDataAdapter.Fill(dt);

    //execute queries, etc
    myConnection.Close();

如果您无法在SharePoint计算机上部署代码,那么您几乎必须使用Web服务.

列表Web服务就是您所追求的.

它将位于http://yousharepointsite.com/_vti_bin/Lists.asmx上,默认情况下应该打开.请注意,如果您的站点配置了FBA,则在查询lists.asmx之前,必须使用_vti_bin/Authentication.asmx登录.

这篇文章提供了您需要的所有信息:

http://sharepointmagazine.net/articles/writing-caml-queries-for-retrieving-list-items-from-a-sharepoint-list

由于上述原因,请跳过使用对象模型查询SharePoint列表的部分,然后直接转到使用SharePoint Web服务检索CAML列表项.

这篇文章非常完整,所以我觉得你应该对此好.

根据您的编辑,我认为您不能像这样创建与远程站点的连接.您无法像这样使用SQL查询SharePoint,您确实需要使用CAML ...

一旦您添加了对Web服务的引用:

ListService listsClient = new ListService.Lists();
listsClient.Url = @"http://sp.markonsolutions.com/" + @"/_vti_bin/lists.asmx";
listsClient.Credentials = System.Net.CredentialCache.DefaultCredentials;
listsClient.GetListItems(...);

就像我说的,你需要使用网络服务.如果您尝试创建类似的连接以直接查询数据库,那么您将走向死胡同.不推荐.

除非您使用适用于SharePoint的ado.net连接器,否则不确定您尝试执行的操作是否可行,请查看http://www.bendsoft.com/net-sharepoint-connector/

它使您可以与SharePoint列表进行通信,就像它们在普通的sql表中一样

在示例中插入一些数据

public void SharePointConnectionExample1()
{
    using (SharePointConnection connection = new SharePointConnection(@"
                Server=mysharepointserver.com;
                Database=mysite/subsite
                User=spuser;
                Password=******;
                Authentication=Ntlm;
                TimeOut=10;
                StrictMode=True;
                RecursiveMode=RecursiveAll;
                DefaultLimit=1000;
                CacheTimeout=5"))
    {
        connection.Open();
        using (SharePointCommand command = new SharePointCommand("UPDATE `mytable` SET `mycolumn` = 'hello world'", connection))
        {
            command.ExecuteNonQuery();
        }
    }
}

或者选择列表数据到DataTable

string query = "SELECT * FROM list";
conn = new SharePointConnection(connectionString);
SharePointDataAdapter adapter = new SharePointDataAdapter(query, conn);

DataTable dt = new DataTable();
adapter.Fill(dt);

或者使用辅助方法填充DataGrid

string query = "Select * from mylist.viewname";
DataGrid dataGrid = new DataGrid();
dataGrid.DataSource = Camelot.SharePointConnector.Data.Helper.ExecuteDataTable(query, connectionString);
dataGrid.DataBind();
Controls.Add(dataGrid);
