给你copy一段:
string filename =Application.StartupPath+@"\信息.xls";
string connstr = @"Provider=Microsoft.Jet.OLEDB.4.0;Extended Properties=Excel 8.0;
Data Source=" + filename + ";Extended Properties='Excel 8.0;HDR=Yes'";//这个链接字符串是excel2003的
OleDbConnection oleConn = new OleDbConnection(connstr);
try
{
oleConn.Open();
string sqlStr;
DataTable dt = oleConn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables_Info, null);
bool existTable = false;
foreach (DataRow dr in dt.Rows)//检查是否有信息表
{
if(dr["TABLE_NAME"].ToString()=="信息表$")//要加个$号
existTable = true;
}
if (!existTable)
{
sqlStr = @"create table 信息表(手机 char(15),姓名 nvarchar(10),生日 char(8),工作 nvarchar(20),邮箱 varchar(30),地址 nvarchar(50))";
OleDbCommand oleCmd = new OleDbCommand(sqlStr, oleConn);
oleCmd.ExecuteNonQuery();
}
string phone = textBox1.Text;
string name = textBox2.Text;
string birthday = comboBox1.Text + "/" + comboBox2.Text + "/" + comboBox3.Text;
string workplace = textBox3.Text;
string email = textBox4.Text;
string address = textBox5.Text;
//下面的代码用OleDbCommand的parameter添加参数
sqlStr = "insert into 信息表 values('"+phone+"','"+name+"','"+birthday+"','"+workplace+"','"+email+"','"+address+"')";
OleDbCommand Cmd = new OleDbCommand(sqlStr, oleConn);
Cmd.ExecuteNonQuery();
}
catch (Exception te)
{
MessageBox.Show(te.Message);
}
finally {
oleConn.Close();
}
