CS0131: 赋值号左边必须是变量、属性或索引器

[sidihu]

protected void vote_Click(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection("server=;database=vote;uid=sa;pwd=sa;");
con.Open();
SqlCommand cmd = new SqlCommand();
cmd.Connection = con;
cmd.CommandText = "update votedetail set votenum=votenum+1 where voteid=" + voteids+"and votedetialid"=this.RadioButtonList1.SelectedValue.ToString();
cmd.ExecuteNonQuery();
con.Close();
}

我想通过点击来更新数据库中数据 但是出现了错误:CS0131: 赋值号左边必须是变量、属性或索引器
出错的的是：cmd.CommandText = "update votedetail set votenum=votenum+1 where voteid=" + voteids+"and votedetialid"=this.RadioButtonList1.SelectedValue.ToString();
麻烦高手指点一下

cmd.CommandText = "update votedetail set votenum=votenum+1 where voteid=" + voteids+"and votedetialid
="+this.RadioButtonList1.SelectedValue.ToString();

and前差一个空格

改为：

cmd.CommandText = "update votedetail set votenum=votenum+1 where voteid=" + voteids+"and votedetialid ="+this.RadioButtonList1.SelectedValue.ToString();
