关于System.Data.SqlClient.SqlException:“'20190103' 附近有语法错误。”的错误

Question

从网上搜说是sql语句有错误，但是感觉应该没有错误

            代码如下
            protected void Button1_Click(object sender, EventArgs e)
    {
        SqlConnection cn = new SqlConnection();
        cn.ConnectionString = ConfigurationManager.ConnectionStrings["connectname"].ConnectionString;
        cn.Open();
        SqlCommand cm = new SqlCommand("insert into student(id,name,num,time,ctime) values('" + this.TextBox1.Text+ "', '" + this.TextBox2.Text + "', '" + this.TextBox3.Text + "', '" + this.TextBox4.Text + "', '" + this.TextBox5.Text+"'",cn);
        cm.ExecuteNonQuery();//这个地方报错
        cn.Close();

求大神解救！！！！
