我认为问题在于你的json响应你的json对象响应应该
"Header":{
CutQuantity = 0;
ETAQuantity = 0;
IDRPrice = 229000;
MasterId = 65639;
Name = "VENICE SATIN DBY 21491 COL 25894";
POQuantity = 0;
ProductCode = "GG01054-14B";
QtyOnHand = "332.1";
ReservedQuantity = "332.1";
SellingPrice = 229000;
TotalAvlQuantity = 0;
USDPrice = 26;
}
和Json数组一样
"Batches" : [
{
AvailableQty = "25.8";
BatchNo = A001;
BinId = 128430;
BinName = "Dummy-700";
DeptId = 23;
DeptName = "G.700";
MaxBodyId = 128430;
ProductCode = "GG01054-14B";
ProductCodeBatch = "GG01054-14B-A001";
ProductId = 65639;
ProductName = "VENICE SATIN DBY 21491 COL 25894";
},
{
AvailableQty = 40;
BatchNo = A002;
BinId = 128433;
BinName = "Dummy-700";
DeptId = 23;
DeptName = "G.700";
MaxBodyId = 128433;
ProductCode = "GG01054-14B";
ProductCodeBatch = "GG01054-14B-A002";
ProductId = 65639;
ProductName = "VENICE SATIN DBY 21491 COL 25894";
}
]

您最大的问题是您的JSON看起来不正确，请将其复制并粘贴到JSON validator中，并确保其正确无误。 此外，请花一些时间来学习JSON - 通过JSON tutorial here。
另外，请检查accepted answer on this question - 它看起来像你真正可以使用的东西，特别是因为你还有/期望数组/值列表。
您的JSON应如下所示：
public static List<String> getList(List<Item> DictionaryItems)
{
UmbracoDatabase db = ApplicationContext.DatabaseContext.Database;
var select = new Sql("SELECT key FROM cmsDictionary");
List<string> DictionaryItems = db.Fetch<Item>(select);
return DictionaryItems;
}
