asp.net导入数据库问题
各位大虾有谁知道怎样把文件导入到数据库里面
比如:文件里面有很多文件每一个文件都要对应到数据库表里面,相当于树结构
如果我没解释清楚的请加我QQ654982114

确实没有说清楚，

文件怎么可能随便就导入数据库？

文件里面有很多文件
＝＝＝＝＝＝＝
如此诡异的文件？

文件里面有很多文件?
现在想在加个文件进去?
头都被你搞晕了。

String tempStr=inputFile.PostedFile.FileName;

String fName=tempStr.Substring(tempStr.LastIndexOf( '\\ ')+1);
int length =tempStr.LastIndexOf( '\\ ')+1;

//另存到本地
inputFile.PostedFile.SaveAs(System.Web.HttpContext.Current.Server.MapPath(ConfigurationSettings.AppSettings[ "CsvPath "])+fName);


//以行为单位
ArrayList Al=new ArrayList();
ArrayList Sl=new ArrayList();

//读取副本得到记录数
String line= " ";
StreamReader sr=new StreamReader(System.Web.HttpContext.Current.Server.MapPath(ConfigurationSettings.AppSettings[ "CsvPath "])+fName,System.Text.Encoding.Default);
while(((line = sr.ReadLine()) != null))
{
if(line.StartsWith( "型号 ")!=true)
{
String newline=line.Replace( '\ ' ', ' ');
Al.Add(newline);
}
}


//存入文件表并返回文件ID

SqlDataLayer dl=new SqlDataLayer();


int fileid=dl.AddDataFile(fName,Al.Count,UserID,tempStr);

//建立插入语句
try

for(int i=0;i <Al.Count;i++)
