我创建一个字典
Dim ImageCollection As New Dictionary(Of ConvensionImages,Integer)
我补充了
For Each dr As DataRow In dt.Rows Dim obj As New ConvensionImages obj.ImageID = dr("ID") obj.Name = dr("Name") obj.Description = dr("Description") obj.CategoryID = dr("CategoryID") obj.CategoryName = dr("CategoryName") obj.CategoryDescription = dr("CatDescription") obj.EventID = dr("EventID") obj.Image = dr("img") obj.DownloadImage = dr("DownLoadImg") ImageCollection.Add(obj,key) key = key + 1
现在我想搜索ImageID和密钥我该怎么做
Make Integer作为您的词典的关键:
Dim ImageCollection As New Dictionary(Of Integer,ConvensionImages)
将ImageCollection.Add(obj,key)更改为ImageCollection.Add(key,obj)
并使用此循环:
For Each kvp As KeyValuePair(Of Integer,ConvensionImages) In ImageCollection Dim v1 As Integer = kvp.Key Dim v2 As ConvensionImages = kvp.Value 'Do whatever you want with v2: 'If v2.ImageID = .... Then Next
