本文實例講述了C#的SQL操作類，分享給大家供大家參考。詳細辦法如下：

{

SqlConnection mycon = new SqlConnection(M_str_sqlcon); //創立銜接對象
return mycon;

SqlConnection sqlcon = this.getcon(); //獲取銜接字符串
sqlcon.Open(); //翻開銜接
try
{
SqlCommand sqlcom = new SqlCommand(M_str_sqlstr, sqlcon); //經過SQL語句和銜接對象創立命令對象
sqlcom.ExecuteNonQuery(); //對sqlcon執行SQL語句並前往受影響的行數
sqlcom.Dispose(); //釋放sqlcom'
}
catch (SqlException e)
{
MessageBox.Show(e.ToString(), "信息提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
finally
{
sqlcon.Close();
sqlcon.Dispose();
}
}
#endregion
#region 創立DataSet對象

SqlDataAdapter sqlda = new SqlDataAdapter(M_str_sqlstr, sqlcon);
DataSet myds = new DataSet();

return myds;
}
#endregion
#region 創立SqlDataReader對象
