I created an object like so:
Object {ABC-123: "XYZ", ABC-112: "LAX"}
and I am trying to send that object to .NET, but I am getting a 500 error, here is how I am sending this object:
$.ajax({
type: "POST",
url: "/vendorProject/api/connection/updateVendorItem",
data: JSON.stringify(editObject),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (data) {
alert('success');
},
failure: function (errMsg) {
alert('failed');
}
});
the variable editObject is the object above. I don't think this part is the problem.
I am sending it to this controller in ASP.NET:
public List<VendorUpdateClass> updateVendorItem(string[] edittedItems)
{
ConnectionClass jobs = new ConnectionClass();
return jobs.updateVendors(edittedItems);
}
and then sending it this class:
public List<VendorUpdateClass> updateVendors(string[] items)
{
VendorUpdateCell = new List<VendorUpdateClass>();
VendorUpdateClass vendorUpdatedItem = new VendorUpdateClass();
for (int i = 0; i < items.Length; i++ ){
vendorUpdatedItem.job = items[i];
vendorUpdatedItem.task = items[i];
vendorUpdatedItem.vendor = items[i];
VendorUpdateCell.Add(vendorUpdatedItem);
}
return VendorUpdateCell;
}
Now here is something interesting when I remove the loop from my class so it looks like so:
public List<VendorUpdateClass> updateVendors(string[] items)
{
VendorUpdateCell = new List<VendorUpdateClass>();
VendorUpdateClass vendorUpdatedItem = new VendorUpdateClass();
//for (int i = 0; i < items.Length; i++ ){
vendorUpdatedItem.job = "aaa";
vendorUpdatedItem.task = "bbb";
vendorUpdatedItem.vendor = "ccc";
VendorUpdateCell.Add(vendorUpdatedItem);
//}
return VendorUpdateCell;
}
this does not give me a 500 error, in fact I get the success alert from the ajax call. So I am assuming I am doing something wrong to loop through my object in .NET Does anyone have any suggestions ?
What I am expecting is vendorUpdatedItem.job
equals ABC-123, vendorUpdatedItem.task
equals ABC-123 and vendorUpdatedItem.vendor
equals XYZ (for the first item anyways)
There is another problem...I can't debug my .NET code as my IIS is not working.
but here is the response I get from my network calls:

Your Javascript object should look something like this:
var vendorUpdatLists= [ { job: "ABC-123", task: "XYZ" }, { job: "ABC-333", task: "LAX" }];
And your method definition should look like:
public List<VendorUpdateClass> updateVendors(List<VendorUpdateClass> vendorUpdateItems) {
// It's time to use the list!
if (vendorUpdateItems != null && vendorUpdateItems.Count() > 0) {
string job = vendorUpdateItems[0].job; // ABC-123
string task = vendorUpdateItems[0].task; // XYZ
}
}
Lastly, I recommend that you follow the proper naming conventions. For example, a public property should start with a capital letter.
string job = vendorUpdateItem.Job;
