导入Excel表时,提示＂找不到可安装的ISAM＂

用c#做导入Excel表时,提示＂找不到可安装的ISAM＂

我百度了下,发现可以如此处理:

1是在连接字符串里面加 HDR=NO;IMEX=1';

2是注册控件: Regsvr32 c:/WINDOWS/system32/msexcl40.dll

string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + FilePath + ";Extended Properties='Excel 8.0;HDR=NO;IMEX=1';";
OleDbConnection conn = new OleDbConnection(strConn);
conn.Open();

string strExcel = "select * from [sheet1$]";
OleDbDataAdapter da = new OleDbDataAdapter(strExcel, strConn);
DataSet ds = new DataSet();

try
{
da.Fill(ds);
}
catch (Exception ex)
{
throw new Exception("读取Excel失败："+ex.Message);
}

return ds;
