我正在使用SuiteTalk为基于NetSuite的应用程序创建后端。我正在尝试计算SalesOrders中的项目总数。
我的问题是,执行搜索操作以获取所有SalesOrders时,返回的Record[]
对象在转换为SalesOrder[]
时(使用Array.ConvertAll(...)
并手动转换)会失去精度。就我而言,这意味着在尝试访问itemList字段时会得到Null Reference异常。
我最终的解决方法如下:
for (SearchResult searchResult = _service.search(salesOrderSearch); searchResult.pageIndex <= searchResult.totalPages; searchResult = _service.searchNext()) {
if (searchResult.status.isSuccess) {
// Convert Record[] to SalesOrder[]. Note that direct conversion causes some fields to become Null
SalesOrder[] salesOrdersNull = Array.ConvertAll(searchResult.recordList, item => (SalesOrder)item);
// To avoid the null issue, send a get request for each order by its internalId
foreach (SalesOrder salesOrderNull in salesOrdersNull) {
SalesOrder salesOrder = getSalesOrder(salesOrderNull.internalId);
// Increment the count by the total number of items
count += salesOrder.itemList.item.Length;
}
} else {
string errorCodes = Helpers.generateErrorString(searchResult.status.statusDetail);
throw new SuiteTalkServiceException("count Sales Order Lines. Failed with error code(s) " + errorCodes);
}
}
但是,这需要为每个销售订单调用get请求,这意味着要花很多时间并且非常不雅致。我还缺少更优雅的解决方案吗?还有其他人遇到过类似的问题吗?还是我很忙?
Record的类定义为:
public abstract partial class Record {
private string[] nullFieldListField;
/// <remarks/>
[System.Xml.Serialization.XmlArrayItemAttribute("name", IsNullable=false)]
public string[] nullFieldList {
get {
return this.nullFieldListField;
}
set {
this.nullFieldListField = value;
}
}
}
SalesOrder的类定义是几千行代码,但是SchemaBrowser entry很清楚。
答案 0 :(得分:1)
我找到了问题here的答案。
从本质上说,为防止itemList
字段变为null
,必须将searchPreferences.bodyFieldsOnly
字段设置为false
。现在,它的运行时间是我的解决方案时间的1/10。
