如何将下拉值作为参数传递给函数
我的代码是

我正在传递这样的价值
受保护 void btnPay_AsPerYourChoice( object sender,EventArgs e)
{
PayWithPayPal(txtAmount,txtPurpose,txtName,txtPhone,txtEmailId,ToString()。(ddlCurrency.SelectedItem));
}
下拉代码是
< asp:DropDownList runat = server < span class =code-attribute> ID = ddlCurrency 样式 = margin-left:42px;
width:204px; background-image:transparent url('../ images / txtBoxbg.jpg')no-repeat ; >

< asp:ListItem > INR < / asp:ListItem >
< asp:ListItem > USD < / asp:ListItem >
< asp:ListItem > EURO < / asp:ListItem >
< asp:Li stItem > Pound < / asp :ListItem >
< / asp:DropDownList >
