Question

似乎在序列化中缺少System.Data.DataSet的DataSetName属性。其他东西，例如嵌入式表和行，看起来也不错。

以下是一个VB.Net单元测试，用于演示非序列化的属性以及各种正确序列化的内容。

    Dim ds = New DataSet, str as String
    Assert.AreEqual("NewDataSet", ds.DataSetName)
    ds.DataSetName = "MyDS"
    Dim dt = New DataTable
    dt.TableName = "MyDT"
    Dim dc = New DataColumn
    dc.ColumnName = "MyDC"
    dc.DataType = GetType(String)
    dt.Columns.Add(dc)
    ds.Tables.Add(dt)
    Dim dr = dt.NewRow
    dr.ItemArray = New Object() {"MyValue"}
    dt.Rows.Add(dr)

    Assert.AreEqual(1, ds.Tables.Count)
    Assert.AreEqual("MyDT", ds.Tables(0).TableName)
    Assert.AreEqual(1, ds.Tables(0).Columns.Count)
    Assert.AreEqual("MyDC", ds.Tables(0).Columns(0).ColumnName)
    Assert.AreEqual(1, ds.Tables(0).Rows.Count)
    Assert.AreEqual("MyValue", ds.Tables(0).Rows(0)(ds.Tables(0).Columns(0)))
    Assert.AreEqual("MyDS", ds.DataSetName)

    str = Newtonsoft.Json.JsonConvert.SerializeObject(ds)
    ds = Newtonsoft.Json.JsonConvert.DeserializeObject(Of DataSet)(str)

    Assert.AreEqual(1, ds.Tables.Count)
    Assert.AreEqual("MyDT", ds.Tables(0).TableName)
    Assert.AreEqual(1, ds.Tables(0).Columns.Count)
    Assert.AreEqual("MyDC", ds.Tables(0).Columns(0).ColumnName)
    Assert.AreEqual(1, ds.Tables(0).Rows.Count)
    Assert.AreEqual("MyValue", ds.Tables(0).Rows(0)(ds.Tables(0).Columns(0)))
    Assert.AreEqual("MyDS", ds.DataSetName, "FAILS - still 'NewDataSet'")

顺便说一句，生成的序列化字符串是

{“ MyDT”：[{“ MyDC”：“ MyValue”}]}

BTW2版本是

Assembly Newtonsoft.Json，版本= 12.0.0.0，文化=中性，PublicKeyToken = 30ad4fe6b2a6aeed

Newtonsoft.Json.JsonConvert.SerializeObject缺少DataSet.DataSetName
