[英]Input string was not in a correct format asp.net
我收到此錯誤,不知道為什么...
這是代碼(注釋中的值)。
protected void FormView1_ItemCommand(object sender, System.Web.UI.WebControls.FormViewCommandEventArgs e)
{
if (e.CommandName == "Update")
{
dsServicesTableAdapters.Select_NegotiateTableAdapter obj = new dsServicesTableAdapters.Select_NegotiateTableAdapter();
//here i am getting the input string is not in a correct format error
obj.Insert_Negotiate_New(Int32.Parse(stockid), //1
Decimal.Parse(txtfobcustomer.Text), //10
Decimal.Parse(txtfrieghtcustomer.Text), //10
Decimal.Parse(txtvanningcustomer.Text), //10
Decimal.Parse(txtinspectioncustomer.Text), //10
Decimal.Parse(txttotal_costcustomer.Text), //10
Int32.Parse(ddlCurrency.SelectedValue), // 0.0105
Int32.Parse(ddlcountry.SelectedValue), //5
Int32.Parse(customerid),//1
txtcustomername.Text, // Anglo
txtcustomerEmail.Text, // Anglo@computers.com
txtcustomer_phone.Text, // 03313752499
txtComments.Text, //test
Int32.Parse(ddlshipmenttye.SelectedValue)); //2
}
}
這是我的存儲過程

任何想法,為什么我得到此錯誤,盡管我猜有正確的值
Int32.Parse(...)
或Decimal.Parse(...)
引發異常。 我首先看到的是:
Int32.Parse(ddlCurrency.SelectedValue), // 0.0105
這顯然不是int
所以使用
Decimal.Parse(ddlCurrency.SelectedValue), // 0.0105
但是,在您的存儲過程中,這似乎也是一個int
因為它是貨幣ID。 然后,您必須修復此錯誤。 當它是一個int-ID時, DropDownList.SelectedValue
不應為0.0105
。
除此之外,如果您當前的文化不使用點,您也將獲得例外.
作為小數點分隔符。 然后,您必須使用InvariantCulture
強制執行此分隔符:
Decimal.Parse(ddlCurrency.SelectedValue, CultureInfo.InvariantCulture)
您正在使用Int32.Parse來解析值,例如0.0105。 如您所知,這不是整數值,因此它將引發異常。 正如我在這里看到的,還有一件事,您正在將int用於@Currency_ID int。 它也應該是金錢或十進制。
