05/13/2015

获取标识该字段引用的 GUID。

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

语法

声明
Public ReadOnly Property Id As Guid
    Get
用法
Dim instance As SPFieldLink
Dim value As Guid

value = instance.Id

public Guid Id { get; }

属性值

类型：System.Guid
该字段引用的唯一标识符。

备注

此属性的值等同于Id属性对应于该字段引用的字段的值。到内容类型的SPFieldCollection属性，以及其SPFieldLinkCollection属性，可以作为索引使用该属性值。

示例

下面的示例演示一个循环访问内容类型SPFieldCollection并打印SPField.Id属性的值，并向控制台的相应SPFieldLink.Id属性的值的控制台应用程序。

Imports System
Imports Microsoft.SharePoint

Module ConsoleApp
    Sub Main()
        Dim site As SPSite = New SPSite("https://localhost")
        Try
            Dim web As SPWeb = site.OpenWeb()
            Try
                Dim contentType As SPContentType = web.ContentTypes("Item")
                For Each field As SPField In contentType.Fields
                    Dim link As SPFieldLink = contentType.FieldLinks(field.Id)
                    Console.WriteLine("Field.Id = {0}", field.Id)
                    Console.WriteLine("FieldLink.Id = {0}", link.Id)
                    Console.WriteLine()
                Next field
            Finally
                web.Dispose()
            End Try
        Finally
            site.Dispose()
        End Try
        Console.Write("Press ENTER to continue...")
        Console.ReadLine()
    End Sub
End Module

using System;
using Microsoft.SharePoint;

namespace Test
{
    class ConsoleApp
    {
        static void Main(string[] args)
        {
            using (SPSite site = new SPSite("https://localhost"))
            {
                using (SPWeb web = site.OpenWeb())
                {
                    SPContentType contentType = web.ContentTypes["Item"];
                    foreach (SPField field in contentType.Fields)
                    {
                        SPFieldLink link = contentType.FieldLinks[field.Id];
                        Console.WriteLine("SPField.Id = {0}", field.Id);
                        Console.WriteLine("SPFieldLink.Id = {0}", link.Id);
                        Console.WriteLine();
                    }
                }
            }
            Console.Write("Press ENTER to continue...");
            Console.ReadLine();
        }
    }
}

应用程序将以下输出显示到控制台上。

Field.Id = c042a256-787d-4a6f-8a8a-cf6ab767f12d
FieldLink.Id = c042a256-787d-4a6f-8a8a-cf6ab767f12d

Field.Id = fa564e0f-0c70-4ab9-b863-0177e6ddd247
FieldLink.Id = fa564e0f-0c70-4ab9-b863-0177e6ddd247

Press ENTER to continue...
