SPField.FieldReferences 属性
获取包含在计算字段引用的字段的内部名称的字符串数组。
命名空间: Microsoft.SharePoint
程序集: Microsoft.SharePoint(位于 Microsoft.SharePoint.dll 中)
语法
声明
Public ReadOnly Property FieldReferences As String()
Get
用法
Dim instance As SPField
Dim value As String()
value = instance.FieldReferences
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();

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.
