CSV文件, 俗称"逗号分隔的文件", 读取CSV文件的方法可以使用IOStream按照即定格式读取...
我以为就这一种方法呢, 呵呵. 直到有一天.在 www.ConnectionStrings.com 上看到文本的连接
字符串:
Text
ODBC
- Standard:
"Driver={Microsoft Text Driver (*.txt; *.csv)};Dbq=c:\txtFilesFolder;Extensions=asc,csv,tab,txt;"
OLE DB
- Standard:
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\txtFilesFolder;Extended Properties=""text;HDR=Yes;FMT=Delimited"""
> _ "HDR=Yes;" indicates that the first row contains columnnames, not data _
* **Standard:**
"Driver={Microsoft Text Driver (*.txt; *.csv)};Dbq=c:\txtFilesFolder;Extensions=asc,csv,tab,txt;"

这里不是有csv么?呵呵,可以试一下啊, 试验结果很不错.可以使用ODBC来连接.把csv当作数据库,
感觉不错.(OleDb的没成功, 将Properties=text改为Properties=csv不好使 
,是不支持,还是我写错?)
因此这里提供一种方法.( 肯定不是我发明的哦 
), 使用ODBC连接方式,通过DataAdapter直接将
数据快速导入DataSet, 很方便.方法如下：
public DataSet GetDataSetFromCSV( string filePath, string fileName)
{
string strConn = @"Driver={Microsoft Text Driver (*.txt; *.csv)};Dbq=";
strConn += filePath; //filePath, For example: C:\
strConn += ";Extensions=asc,csv,tab,txt;" ;
OdbcConnection objConn = new OdbcConnection(strConn);
DataSet dsCSV = new DataSet();
try
{
string strSql = "select * from " + fileName; //fileName, For example: 1.csv
OdbcDataAdapter odbcCSVDataAdapter = new OdbcDataAdapter(strSql, objConn);
odbcCSVDataAdapter.Fill(dsCSV);
return dsCSV;
}
catch (Exception ex)
{
throw ex;
}
}
