序列化:
Dim dataSet As dataSet = New DataSet("dataSet")
dataSet.[Namespace] = "NetFrameWork"
Dim table As New DataTable()
Dim idColumn As New DataColumn("id", GetType(Integer))
idColumn.AutoIncrement = True
Dim itemColumn As New DataColumn("item")
table.Columns.Add(idColumn)
table.Columns.Add(itemColumn)
dataSet.Tables.Add(table)
Dim i As Integer = 0
While i < 2
Dim newRow As DataRow = table.NewRow()
newRow("item") = "item " + i
table.Rows.Add(newRow)
i += 1
End While
dataSet.AcceptChanges()
Dim json As String = JsonConvert.SerializeObject(dataSet, Formatting.Indented)
反序列:
Dim json As String = IO.File.ReadAllText(HttpContext.Current.Server.MapPath("~/Data.json"))
Dim dt As New System.Data.DataTable
dt = Newtonsoft.Json.JsonConvert.DeserializeObject(Of DataTable)(json)
