我怎样才能解决这个错误？ [英] How Can I Solve The Errors In This?
问题描述
我在void pageload（），viewstate [add]，newbutton2，事件处理程序以及之后的括号中得到错误。帮帮我。！
使用系统;
使用System.Collections.Generic;
使用System.Linq;
使用System.Web;
使用System.Web.UI;
使用System.Web.UI.WebControls;
使用System.Data.SqlClient;
使用System.Data;
使用System.IO;
使用System.Configuration;
public partial class _Default：System.Web.UI.Page
{
SqlConnection con = new SqlConnection（ConfigurationManager.ConnectionStrings [conn]。ConnectionString）;
SqlCommand cmd = new SqlCommand（）;
}
protected void Page_Load（object sender，EventArgs e）
{
if（IsPostBack）
{
if（ViewState [Add]！= null）
{
Button add = new Button2（）;
add.Text =Add;
add.Click + = new EventHandler（add_Click）;
PlaceHolder1.Controls.Add（add）;
}
if（ViewState [textboxes]！= null）
{
int count = 0;
count =（int）ViewState [textboxes];
for（int i = 0;我<计数; i ++）
{
TextBox textbox_foradd = new TextBox（）;
textbox_foradd.ID =textadd+（i + 1）.ToString （）;
PlaceHolder1.Controls.Add（textbox_foradd）;
}
}
}
}
void add_Click（object sender，EventArgs e）
{
int count = 1;
if（ViewState [textboxes]！= null）
{
count + = Convert.ToInt32（ViewState [ textboxes]）;
}
TextBox textbox_foradd = new TextBox（）;
textbox_foradd.ID =textadd+ count.ToString（ ）;
PlaceHolder1.Controls.Add（textbox_foradd）;
ViewState [textboxes] = count;

带走紧密的花括号，在行后立即关闭你的班级：
SqlCommand cmd = new SqlCommand（）;
并将其移至底部文件。 ：笑：

Take away the close curly bracket which closes your class immediately after the line:
SqlCommand cmd = new SqlCommand();
and move it to the bottom of the file. :laugh:
