Question

我设法添加了一个联系人但是当我尝试添加发票时，我收到一条错误消息＆＃39;发生了验证异常＆＃39;。我希望得到关于导致此错误的原因的建议。

private void button1_Click(object sender, EventArgs e)
{
    try
    {
        /// first create an instance of the Xero API
        var api = new Xero.Api.Example.Applications.Private.Core(false);

        Contact newContact = new Contact();
        newContact.Name = "Orac"; 
        Invoice newInvoice = new Invoice();
        newInvoice.Contact = new Contact();
        newInvoice.Contact = newContact;
        newInvoice.Date = System.DateTime.Now;
        newInvoice.DueDate = System.DateTime.Now.AddMonths(1);
        newInvoice.Status = Xero.Api.Core.Model.Status.InvoiceStatus.Authorised;
        newInvoice.Type = Xero.Api.Core.Model.Types.InvoiceType.AccountsReceivable;
        List<LineItem> lines = new List<LineItem>();
        LineItem li = new LineItem();
        li.LineAmount = Convert.ToDecimal("200.00");
        li.Quantity = Convert.ToDecimal("1.0000");
        li.ItemCode = "100";
        li.Description = "Webdev inv test";
        li.AccountCode = "200";
        li.UnitAmount = Convert.ToDecimal("50.00");
        lines.Add(li);
        newInvoice.LineItems = lines;

        // call the API to create the contact
        api.Invoices.Create(newInvoice);
        //api.Contacts.Create(newContact);
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }

Answer 1

保留您的创作请求的结果 - 例如

var result = api.Invoices.Create(newInvoice);

...并检查结果的错误和警告属性，以确定您的请求有什么问题。

Answer 2

抛出的异常类型是ValidationException。要么专门捕获该类型，要么强制转换捕获的通用异常，并检查ValidationErrors属性
