Question

以下是使用Json.NET的JSON输出。为什么所有的＆＃34; \＆＃34;被插入？

输出

{\"titles\":[{\"lesson\":1.0,\"title\":\"Objectives\"},{\"lesson\":2.0,\"title\":\"What are Cars?\"},{\"lesson\":3.0,\"title\":\"The Role of Cars\"}],\"objective\":[{\"objective\":\"Describe cars.\"},{\"objective\":\"Describe the role of cars.\"},{\"objective\":\"Define cars.\"}]}

代码

    Dim dst As DataSet = db.ExecuteDataSet(dbCommand)
    Dim sb As New StringBuilder()
    Dim sw As New StringWriter(sb)
    Dim writer As JsonWriter = New JsonTextWriter(sw)

    writer.WriteStartObject()

    If dst.Tables(1).Rows.Count > 0 Then
        writer.WritePropertyName("titles")
        writer.WriteStartArray()
        For i As Integer = 0 To 2
            writer.WriteStartObject()
            writer.WritePropertyName("lesson")
            writer.WriteValue(dst.Tables(1).Rows(i).Item("lesson"))
            writer.WritePropertyName("title")
            writer.WriteValue(dst.Tables(1).Rows(i).Item("title").ToString)

            writer.WriteEndObject()
        Next
        writer.WriteEndArray()
    End If

    If dst.Tables(2).Rows.Count > 0 Then
        writer.WritePropertyName("objective")
        writer.WriteStartArray()
        For i As Integer = 0 To 2
            writer.WriteStartObject()
            writer.WritePropertyName("objective")
            writer.WriteValue(dst.Tables(2).Rows(i).Item("objective"))

            writer.WriteEndObject()
        Next
        writer.WriteEndArray()
    End If
    writer.WriteEndObject()

你得到所有“\”字符的原因是因为你只有一个字符串。该字符串需要像这样解析

JObject root = JObject.Parse('your_string_here');

我希望这会对你有所帮助。

Json.net输出JSON包含＆＃34; \＆＃34;人物？
