提供了无效的参数“当我尝试使用SharePoint客户端对象模型和.NET应用程序在线连接sharepoint时出现错误 [英] An invalid argument was supplied" error when I try to connect sharepoint online using SharePoint Client Object Model with .NET application
问题描述
我正在尝试通过c#.net代码在线连接SharePoint(办公365云基础).我正在使用"Microsoft.SharepointOnline.CSOM"； NuGet软件包版本V16.1.7414.1200和应用程序.net框架4.5.2. 我已经在Google上尝试了所有不同类型的代码.没什么对我有用.
I am trying to connect SharePoint online (office 365 cloud base) through c#.net code.I am using "Microsoft.SharepointOnline.CSOM" NuGet package version V16.1.7414.1200 and application .net framework 4.5.2. I already tried all different type of code by looking on google. nothing is working for me.
在这里，我尝试了所有示例代码.
示例代码1
使用 ( ClientContext clientContext = 新 ClientContext
using (ClientContext clientContext = new ClientContext("https://xxx.com"))
{
var psd = 密码"
var psd = "password".ToCharArray();
SecureString 新 SecureString
SecureString secureString = new SecureString();
foreach ( char in
foreach (char c in psd) secureString.AppendChar(c);
//psd.ToList().ForEach(secureString.AppendChar);
//psd.ToList().ForEach(secureString.AppendChar);
clientContext.Credentials = 新 SharePointOnlineCredentials 用户名"
clientContext.Credentials = new SharePointOnlineCredentials("username", secureString);
//Web oWeb = clientContext.Web;
// Web oWeb = clientContext.Web;
列表 标题" )；
List oList = clientContext.Web.Lists.GetByTitle("Title");
CamlQuery 新 CamlQuery
CamlQuery camlQuery = new CamlQuery();
camlQuery.ViewXml = < View>< RowLimit> 100</RowLimit></View>" ;
camlQuery.ViewXml = "<View><RowLimit>100</RowLimit></View>";
ListItemCollection
ListItemCollection collListItem = oList.GetItems(camlQuery);
clientContext.Load(collListItem，
项目=> items.Include(
&bb ; item => item.Id，
; item => item.DisplayName，
; item => item.HasUniqueRoleAssignments));
clientContext.ExecuteQuery();
foreach ( ListItem in
foreach (ListItem oListItem in collListItem)
{
; 控制台 @" ID: {0} {1} {2} ，
Console.WriteLine(@"ID: {0} \nDisplay name: {1} \nUnique role assignments: {2}",
; oListItem.Id，oListItem.DisplayName，oListItem.HasUniqueRoleAssignments)；
}
; }
示例代码2
使用 ( ClientContext spcontext = 新 ClientContext
using (ClientContext spcontext = new ClientContext(siteurl))
{
spcontext.AuthenticationMode = ClientAuthenticationMode
spcontext.AuthenticationMode = ClientAuthenticationMode.FormsAuthentication;
spcontext.FormsAuthenticationLoginInfo = 新 FormsAuthenticationLoginInfo 用户名" 密码"
spcontext.FormsAuthenticationLoginInfo = new FormsAuthenticationLoginInfo("username", "password");
spcontext.Load(spcontext.Web，w => w.Title，w => w.ServerRelativeUrl，w => w.Lists);
尝试
try
{
; spcontext.ExecuteQuery();
&bb ; 控制台
Console.WriteLine(spcontext.Web.ServerRelativeUrl);
}
捕获 ( 异常
catch (Exception ex)
{
; //throw;
//throw;
}
; }
我在所有示例代码上始终都遇到错误.
I am getting the error all the times on all sample codes.
仅供参考-我的计算机上没有代理设置

因此，我还更改了我的app.config文件中的默认代理设置.
< system.net>
< defaultProxy enabled ="false"； useDefaultCredentials ="false">
< proxy/>
< bypasslist>
<添加地址＝"[a-z] + \.[a-z] + \.[a-z] +". />
</bypasslist>
< module/>
</defaultProxy>
</system.net>
但是在更改了上面的配置设置之后，我得到了以下错误提示.
基础连接已关闭:无法连接到远程服务器.
内部异常一直存在，如下所示.

推荐答案
这是代理服务器的问题，您的网络正在使用代理服务器.
It is the problem of proxy server and your network is using proxy server.
我们需要如下设置代理服务器的IP和端口号.
We need to set the IP and Port number of proxy server as below.
<system.net>
<defaultProxy>
<proxy proxyaddress="http://[Proxy IP Address]:[Proxy Port Number]" bypassonlocal="True" />
</defaultProxy>
</system.net>
此外，关于如何进行身份验证以访问CSOM中的SharePoint Online，以下是一个演示.
In addition, About how to do authentication to access SharePoint online in CSOM, here is a demo as below.
public static void setOnlineCredential(ClientContext clientContext,string userName,string password)
{
//set the user name and password
SecureString secureString = new SecureString();
foreach (char c in password.ToCharArray())
{
secureString.AppendChar(c);
}
clientContext.Credentials = new SharePointOnlineCredentials(userName, secureString);
}
