JSON数组未填充

出于某种原因,下面的JSON字符串在自定义对象数组中创建正确数量的记录,但不会用和值填充数组中的对象。感谢您的帮助!

JSON字符串

{ 
"Grids": [{ "CommitImporterGrid": {"CostDivisionCode": "DL", "CostDivisionKey": 5, "CostDivisionName": "Direct Labor", "SourceType": "Contractor", "CommitDollars": 202, "CommitHours": 113.12, "PercentComplete": 50.00, "TaxRate": 0, "IohRate": 0.01, "ConditionerRate": 0}}],
"ProjectKey": 571, 
"AsOf": "1/1/2008 11:59:59 PM", 
"WbsKey": 1327, 
"FcrGroupKey": 26, 
"ContractorKey": 11
}

反序列化程序

protected void btnSave_Click(object sender, EventArgs e)
{
    JavaScriptSerializer serializer = new JavaScriptSerializer();
    JsonViewer view = serializer.Deserialize<JsonViewer>(txtJson.Value);

    // The LIST in the "view" object HAS records, but NO DATA?
}

自定义类

public class JsonViewer
{
    public JsonViewer()
    { }

    public List<CommitImporterGrid> Grids { get; set; }

    public Int32 ProjectKey { get; set; }
    public String AsOf { get; set; }
    public Int32 WbsKey { get; set; }
    public Int32 FcrGroupKey { get; set; }
    public Int32 ContractorKey { get; set; } 
}



public class CommitImporterGrid
        {
            public CommitImporterGrid()
            { }

            public String CostDivisionCode { get; set; } 
            public Int32 CostDivisionKey { get; set; } 
            public String CostDivisionName { get; set; } 
            public String SourceType { get; set; } 
            public Decimal CommitDollars { get; set; } 
            public Decimal CommitHours { get; set; } 
            public Decimal PercentComplete { get; set; } 
            public Decimal TaxRate { get; set; } 
            public Decimal IohRate { get; set; } 
            public Decimal ConditionerRate { get; set; } 
        }
