Following C# code I want to use in newform page source using sharepoint designer

   SPSite _site = SPContext.Current.Site;
   ServerContext serverContext = ServerContext.GetContext(_site);
   UserProfileManager myUserProfile = new UserProfileManager(serverContext);
   UserProfile currentUserProfile = myUserProfile .GetUserProfile(System.Web.HttpContext.Current.User.Identity.Name);

   string departmentName = (string)currentUserProfile["department"].Value;
   string managerName = (string)currentUserProfile["manager"].Value;
   _site.RootWeb.Dispose();
   _site.Dispose();

推荐答案

SharePoint Designer 删除了各种类型的代码，包括所有 C#，以防止意外引入漏洞.要使用 C# 代码，您需要使用 VIsual Studio 创建和部署解决方案包.相反，您最好的选择可能是使用 JavaScript.这里是 2013 年的文档，这里是一个简化 2010 年数据检索的实用程序 和 这里是一些代码可以让你非常接近你想要做的事情.

SharePoint Designer removes various types of code, including all C#, in order to prevent vulnerabilities from accidentally being introduced. To use your C# code you will need to create and deploy a solution package with VIsual Studio. Instead, your best bet is probably to use JavaScript. Here is documentation for 2013, here is a utility to simplify retrieving the data in 2010, and here is some code that will get you very close to what you're trying to do.

<script type="text/javascript">
// ensure system stuff is loaded before we start calling client object model
ExecuteOrDelayUntilScriptLoaded(getWebUserData, "sp.js");

// create context variables
var context = null;
var web = null;
var currentUser = null;

// this function calls object model to determine current user name
function getWebUserData() {
context = new SP.ClientContext.get_current();
web = context.get_web();
currentUser = web.get_currentUser();
currentUser.retrieve();
context.load(web);
context.executeQueryAsync(Function.createDelegate(this, this.onSuccessMethod),  
Function.createDelegate(this, this.onFailureMethod));
}

// this function gets called if we get current user name successfully
function onSuccessMethod(sender, args) {
var loginName = web.get_currentUser().get_loginName();

// this call requests the value for property named "Title" for current user name
GetUserProperty(loginName, "Title");
}

// yes, things failed; I ignore it here but you can display an alert
function onFailureMethod(sender, args) {
// Unable to find user profile
} 

// function which retrieves the value of the property
function GetUserProperty(accountName, propertyName) {

// constructing the call to a user profile using web services
var soapMessage = '<?xml version="1.0" encoding="utf-8"?>'
  + '<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:xsd="http://www.w3.org/2001/XMLSchema"
  xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">'
  + '<soap:Body>'
  + ' <GetUserPropertyByAccountName
   xmlns="http://microsoft.com/webservices/SharePointPortalServer/UserProfileService">'
  + '  <accountName>' + accountName + '</accountName>'
  + '  <propertyName>' + propertyName + '</propertyName>'
  + ' </GetUserPropertyByAccountName>'
  + ' </soap:Body>'
  + '</soap:Envelope>'

// making a call with jQuery
$.ajax({  
url: '/_vti_bin/UserProfileService.asmx',  
type: "POST",  
dataType: "xml",  
data: soapMessage,  
complete: displayProfileProperty,  
contentType: "text/xml; charset=\"utf-8\"" 
}); 
return false; 
}

// things went well and we get results back
function displayProfileProperty(xmlHttpRequest, status)  
{  
// the result is burried in XML markup so we look for the right node
$(xmlHttpRequest.responseXML).find('Values').each(function()  
{  
// get the text property of the node and display it
var name = $(this).find('Value').text(); 
alert(name); 
}); 
}
