我写的

使用（SPSite 站点 = SPContext.Current.Site） { 使用 (SPWeb web = site.OpenWeb()) { //SPList lst = web.Lists["ManagerInfo"]; SPList lst = web.Lists[strlist];

                      SPQuery getUserNameQuery = new SPQuery();
                      // getUserNameQuery.Query = "<Where><And><Eq><FieldRef Name=\"Region\" /><Value Type=\"Text\">" + strRegion + "</Value></Eq><And><Eq><FieldRef Name=\"PM_x0020_First_x0020_Name\" /><Value Type=\"Text\">" + pmFName + "</Value></Eq><Eq><FieldRef Name=\"PM_x0020_Last_x0020_Name\" /><Value Type=\"Text\">" + pmLname + "</Value></Eq></And></And></Where>";
                       // getUserNameQuery.Query = "<Where><And><Eq><FieldRef Name=\"PM_x0020_First_x0020_Name\" /><Value Type=\"Text\">" + pmFName + "</Value></Eq><Eq><FieldRef Name=\"PM_x0020_Last_x0020_Name\" /><Value Type=\"Text\">" + pmLname + "</Value></Eq></And></Where>";

                       getUserNameQuery.Query = "<Where><Eq><FieldRef Name=\"PM_x0020_Name\" /><Value Type=\"Text\">" + loginName  + "</Value></Eq></Where>";

                      SPListItemCollection items = lst.GetItems(getUserNameQuery);
                      foreach (SPListItem item in items)
                      {
                          managerFName = item["Manager Name"].ToString();
                          strAccounting = item["Accounting"].ToString();

                          managerFName = managerFName.Replace(".", " ");
                          strAccounting = strAccounting.Replace(".", " ");
                          // isFound = true;
                          XPathNavigator managerName = MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:txtManagerName", NamespaceManager);
                          managerName.SetValue(managerFName);
                          XPathNavigator accountingName = MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:txtAccountingName", NamespaceManager);
                          accountingName.SetValue(strAccounting);
                      }

} }

我在 infopath 中使用了这个代码，这个 infopath 被所有 users.os 使用，当当前登录用户对它显示错误的列表没有权限时。当当前登录用户有完全权限时，它正在工作。所以请告诉我我该怎么做才能为所有用户使用它们。

通过使用这个

使用（SPSite 站点 = SPContext.Current.Site）{}

您正在处理不应执行的 SPContext.Current.Site。考虑到 Don 的建议，试试这个

SPSecurity.RunWithElevatedPrivileges(delegate()
{
    using (SPSite site = new SPSite(SPContext.Current.Site.ID))
    {
        using (SPWeb web = site.OpenWeb(SPContext.Current.Web.ID))
        {

            //SPList lst = web.Lists["ManagerInfo"]; 
            SPList lst = web.Lists[strlist];

            SPQuery getUserNameQuery = new SPQuery();
            // getUserNameQuery.Query = "<Where><And><Eq><FieldRef Name=\"Region\" /><Value Type=\"Text\">" + strRegion + "</Value></Eq><And><Eq><FieldRef Name=\"PM_x0020_First_x0020_Name\" /><Value Type=\"Text\">" + pmFName + "</Value></Eq><Eq><FieldRef Name=\"PM_x0020_Last_x0020_Name\" /><Value Type=\"Text\">" + pmLname + "</Value></Eq></And></And></Where>"; 
            // getUserNameQuery.Query = "<Where><And><Eq><FieldRef Name=\"PM_x0020_First_x0020_Name\" /><Value Type=\"Text\">" + pmFName + "</Value></Eq><Eq><FieldRef Name=\"PM_x0020_Last_x0020_Name\" /><Value Type=\"Text\">" + pmLname + "</Value></Eq></And></Where>"; 

            getUserNameQuery.Query = "<Where><Eq><FieldRef Name=\"PM_x0020_Name\" /><Value Type=\"Text\">" + loginName + "</Value></Eq></Where>";

            SPListItemCollection items = lst.GetItems(getUserNameQuery);
            foreach (SPListItem item in items)
            {
                managerFName = item["Manager Name"].ToString();
                strAccounting = item["Accounting"].ToString();

                managerFName = managerFName.Replace(".", " ");
                strAccounting = strAccounting.Replace(".", " ");
                // isFound = true; 
                XPathNavigator managerName = MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:txtManagerName", NamespaceManager);
                managerName.SetValue(managerFName);
                XPathNavigator accountingName = MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:txtAccountingName", NamespaceManager);
                accountingName.SetValue(strAccounting);
            }
        }
    }
});

【解决方案2】：

尝试用 :

包围你的代码逻辑

SPSecurity.RunWithElevatedPrivileges(delegate()
{
    // insert code here
}
