在我的表单中，用户从下拉框中选择客户。我将客户发票填入gridview。现在我想将发票号和发票金额存储到数组中。如何完成这项任务？ 我尝试了这段代码但只获得了最后一行gridview

Hi, In my form user select the customer from dropdown box. I populate the customer invoice's into gridview. Now I want to store that invoice no and invoice amount into array. How to complete this task ? I tried this code but getting last row of gridview only

for (int i = 0; i < gridView2.RowCount; i++) { invno = gridView2.GetRowCellValue(i, "InvoiceId"); int[] invid = new int[] { Convert.ToInt32(invno) }; }

推荐答案

在这里，您可以找到有关.NET和C＃中数组的一些信息： msdn.microsoft/en-us/library/ aa288453％28v = vs.71％29.aspx [ ^ ] 我认为在这种情况下，数组不是一个好选择。为什么不使用Dictionary？ 假设您在gridView中存储数据，如下所示：InvoiceId（Int32）和TotalAmount（Double），请尝试使用此代码： Here you find some informations about arrays in .NET and C#: msdn.microsoft/en-us/library/aa288453%28v=vs.71%29.aspx[^] I think that array is not good choice in this case. Why not to use Dictionary? Assuming that you are storing data in gridView in fields like this: InvoiceId (Int32) and TotalAmount (Double), try to use this code: var invoices = new Dictionary<int,double>() for (int i = 0; i < gridView2.RowCount; i++) { invNo = gridView2.GetRowCellValue(i, "InvoiceId"); invAmount = gridView2.GetRowCellValue(i, "TotalAmount"); invoices.Add(invNumber, invAmount); }

您可以像这样迭代字典：

The you can iterate through you dictionary like this:

foreach (int invoiceId in invoices.Keys) { double invoiceAmount = invoices[invoiceId] Console.WriteLine(string.Format("Invoice: {0}, Total amount: {1}", invoiceId, invoiceAmount)); }
