本文實(shí)例講述了asp.net實(shí)現(xiàn)批量刪除功能的方法。對(duì)于asp.net的學(xué)習(xí)有一定的參考價(jià)值。分享給大家供大家參考之用。具體實(shí)現(xiàn)方法入戲：

protected void btndeleteall_Click(object sender, EventArgs e)
{
string sqltext = "(";
for (int i = 0; i GridView1.Rows.Count; i++)
{
CheckBox chb = (CheckBox)GridView1.Rows[i].FindControl("id");
if (chb.Checked)
{
sqltext = sqltext + GridView1.DataKeys[i].Value.ToString() + ",";
}
}
sqltext = sqltext.Substring(0, sqltext.Length - 1) + ")";
sqltext = "delete from shangpu where id in" + sqltext;
string sqlcon = ConfigurationManager.AppSettings["ConnectionString"].ToString();
SqlConnection con = new SqlConnection(sqlcon);
con.Open();
SqlCommand cmd = new SqlCommand(sqltext, con);
try
{
int count = Convert.ToInt32(cmd.ExecuteNonQuery());
if (count > 0)
{
viewbind();
MessageBox.Show(this, "刪除成功,共刪除" + count + "條記錄！");
}
}
catch
{
MessageBox.Show(this, "刪除失敗！");
}
finally
{
con.Close();
con.Dispose();
}
}
感興趣的朋友可以調(diào)試運(yùn)行一下本文實(shí)例，學(xué)有余力的朋友還可以對(duì)代碼作出改進(jìn)以完善其功能。希望本文實(shí)例對(duì)大家的asp.net學(xué)習(xí)有一定的幫助作用。
