Public ReadOnly Property FieldReferences As String()
    Get
用法
Dim instance As SPField

public string[] FieldReferences { get; }

属性值

类型：[]
返回 String。

示例

下面的代码示例显示涉及字段引用的字段的内部名称。

此示例假定存在包含标签控件的 .aspx 页。

此示例要求对Microsoft.SharePoint和Microsoft.SharePoint.Utilities命名空间的using指令 （在 Visual Basic 中的Imports )。

Dim site As SPSite = SPContext.Current.Site
Dim web As SPWeb = site.AllWebs("Site_Name")
Dim fields As SPFieldCollection = web.Lists("List_Name").Fields
Dim i As Integer

For i = 0 To fields.Count - 1

    Dim refFields As String() = fields(i).FieldReferences

    If Not (refFields Is Nothing) Then

        Dim j As Integer

        For j = 0 To refFields.Length - 1

            Label1.Text += SPEncode.HtmlEncode(refFields(j)) & "<BR>"

        Next j

    End If

Next i

SPSite oSiteCollection = SPContext.Current.Site;
SPWeb oWebsite = oSiteCollection.AllWebs["Site_Name"];
SPFieldCollection collFields = oWebsite.Lists["List_Name "].Fields;

for (int intIndex=0; intIndex<collFields.Count; intIndex++)
{
    string[] strRefFields = collFields[intIndex].FieldReferences;

    if (strRefFields != null)
    {
        for (int intStrPos=0; intStrPos<strRefFields.Length; intStrPos++)
        {
            Label1.Text += SPEncode.HtmlEncode(strRefFields[intStrPos]) + "<BR>";
        }
    }
}
oWebsite.Dispose();

备注

Certain objects implement the IDisposable interface, and you must avoid retaining these objects in memory after they are no longer needed. For information about good coding practices, see Disposing Objects.
