'用途
Dim instance As SPListItemVersionCollection

public sealed class SPListItemVersionCollection : SPBaseCollection

備註

使用SPListItem類別的Versions屬性，傳回集合的清單項目的版本。

使用索引子來從集合傳回單一版本。例如，如果集合指派給一個名為collListItemVersions變數中，使用在 C# 的collListItemVersions[index]或collListItemVersions(index)index所在集合中的版本編號的 Visual Basic 中。index，較低的值較新版本。

Examples

下列程式碼範例逐一查看清單中的項目，並還原先前的版本的項目，如果目前的版本中的欄位等於指定的值。

Dim list As SPList = New SPSite("http://MySiteCollection").AllWebs("MyWebSite").GetList("http://MySiteCollection/MyWebSite/Lists/MyList")
Dim listItems As SPListItemCollection = list.Items

Dim item As SPListItem
For Each item In listItems
    If CStr(item("Title")) = "MyValue" Then
        Dim versions As SPListItemVersionCollection = item.Versions

        If versions.Count > 1 Then
            versions.Restore(1)
        End If
    End If 
Next item

SPList oList = new SPSite("http://MySiteCollection").AllWebs["MyWebSite"].GetList("http://MySiteCollection/MyWebSite/Lists/MyList");

SPListItemCollection collListItems = oList.Items;

foreach (SPListItem oListItem in collListItems)
{
    if ((string)oListItem["Title"] == "MyValue")
    {
        SPListItemVersionCollection collListItemVersions = 
            oItem.Versions;

        if (collListItemVersions.Count > 1)
        {
            collListItemVersions.Restore(1);
        }
}
