通过

ObjectChangeConflict.Resolve 方法 (RefreshMode)

  • 项目

通过指定每个字段和属性，这些属性的差异，一个值到下一次的SubmitChanges上的数据库保持不变，解决矛盾。

命名空间：  Microsoft.SharePoint.Linq
程序集：  Microsoft.SharePoint.Linq（位于 Microsoft.SharePoint.Linq.dll 中）

语法

声明
Public Sub Resolve ( _
    refreshMode As RefreshMode _
)
用法
Dim instance As ObjectChangeConflict
Dim refreshMode As RefreshMode

instance.Resolve(refreshMode)

public void Resolve(
    RefreshMode refreshMode
)

参数

备注

Resolve(RefreshMode)方法的此重载行为完全按照Resolve(RefreshMode, Boolean)与autoResolveDeletes参数设置为true。

示例

下面的示例演示如何在catch块中使用Resolve(RefreshMode) ，对ChangeConflictException进行响应：

foreach (TeamMember teamMember in teamSite.TeamMembers)
{
    teamMember.TopTask = "Fiscal Planning";
}

try 
{
    teamSite.SubmitChanges(ConflictMode.ContinueOnConflict);
}
catch (ChangeConflictException e) 
{
    foreach (ObjectChangeConflict changedListItem in teamSite.ChangeConflicts)
    {
        // If another user has changed properties of a non-manager,
        // leave that other user’s changes, except for the TopTask field.
        if (((TeamMember)changedListItem.Object).IsManager = false)
        {        
             foreach (MemberChangeConflict changedField in changedListItem.MemberConflicts)
            {
                if (changedField.Member.Name == "TopTask")
                {
                    changedField.Resolve(RefreshMode.KeepCurrentValues);
                }
                else
                {
                    changedField.Resolve(RefreshMode.OverwriteCurrentValues);
                }
            }
        }
        // But if another user has changed properties of a manager, let this
        // process’s changes override the other user’s changes.
        else
        {
            changedListItem.Resolve(RefreshMode.KeepCurrentValues);
        }    
    }

    teamSite.SubmitChanges();
} // end catch
