bool exist = System.IO.File.Exists(@"C:\ConfigRecord.xls");

if(exist)
{
System.IO.File.Delete(@"C:\ConfigRecord.xls");
}

object missing = System.Reflection.Missing.Value;

Excel.ApplicationClass myExcel = new Excel.ApplicationClass();

Excel._Workbook xBk ; //工作薄

xBk = myExcel.Workbooks.Add(true);

xBk.SaveAs(@"C:\ConfigRecord.xls",missing,missing,
missing,missing,missing,Excel.XlSaveAsAccessMode.xlShared,
missing,missing,missing,missing,missing);

myExcel.Quit();

OleDbConnection excelConn = new OleDbConnection();
excelConn.ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\ConfigRecord.xls; Extended Properties=Excel 8.0;";

excelConn.Open();

OleDbCommand oleExcelCommand=new OleDbCommand ();
oleExcelCommand.Connection =excelConn;

string basicInfotableName;
basicInfotableName="deviceInfo_BaseInfo";
sql="drop table " + basicInfotableName + ";";
oleExcelCommand.CommandText=sql;
try
{
oleExcelCommand.ExecuteNonQuery();
}
catch(System.Data.OleDb.OleDbException ex)
{

}

sql="create table "+basicInfotableName+" (DeviceType char, WholeDeviceCode char primary key";
sql=sql+");";
oleExcelCommand.CommandText=sql;

try
{
oleExcelCommand.ExecuteNonQuery();
}
catch(System.Data.OleDb.OleDbException ex)
{
MessageBox.Show(this,"创建数据库失败","提示信息",MessageBoxButtons.OK,MessageBoxIcon.Information);
}

总是提示“创建数据库失败”
说未找到表deviceInfo_BaseInfo
