建好应用程序，运行程序在添加数据库时，提示列名错误是哪里出了问题啊？

private void button1_Click(object sender, System.EventArgs e)
{

try
{
if(this.textBox1.Text!="" &this.textBox2.Text!="" &this.textBox3.Text!="" &this.textBox4.Text!="" &this.textBox5.Text!="" &this.textBox6.Text!="" &this.textBox7.Text!="" &this.textBox8.Text!="" &this.textBox9.Text!="")
{
SqlConnection thisConnection=new SqlConnection(@"Data Source=(local);Integrated Security=SSPI;"+"Initial Catalog=student");



string insert= " INSERT INTO 成绩 (学号,姓名,性别,出生日期,籍贯,政治面貌,民族,毕业时间,就业情况,就业单位) VALUES ('" ;

insert += this.textBox1.Text + "', '";
insert += this.textBox2.Text + "', '";
insert += this.textBox3.Text + "', '";
insert += this.textBox4.Text + "', '";
insert += this.textBox5.Text + "', '";
insert += this.textBox6.Text + "', '";
insert += this.textBox7.Text + "', '";
insert += this.textBox8.Text + "', '";
insert += this.textBox9.Text + "', '";
insert += this.textBox10.Text + "') ";

//初始化OleDbCommand
SqlCommand comm=new SqlCommand();
comm.CommandText=insert;
comm.Connection=thisConnection;

//打开数据库连接
thisConnection.Open();
//执行添加记录的语句
comm.ExecuteNonQuery();
//关闭记录
thisConnection.Close();
}
else
MessageBox.Show("*号必须添完整","提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
}
catch(Exception ed)
{
MessageBox.Show("添加记录发生错误："+ed.Message,"提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
}

}
代码有没有错啊，帮我看看吧，应该不是数据库问题吧，我在查询的时候可以啊
添加的时候性别出了问题
