类文件有没有用vb写的?
nnh 2006-05-16 05:12:22 在网上看到很多asp.net的类,都是用c#写的.如:
public string Extension
{
get
{
if(extension!="") return extension;
return "txt";
}
set
{
extension=value;
}
}
public string PathToName(string path)
{
int pos=path.LastIndexOf("\\");
return path.Substring(pos+1);
}
public string Upload()
{
if(PostedFile!=null)
{
try{
string fileName=PathToName(PostedFile.FileName);
if(!fileName.EndsWith(Extension)) return "You must select "+Extension+" file!";
if(PostedFile.ContentLength>FileLength) return "File too big!";
PostedFile.SaveAs(SavePath+fileName);
return "Upload File Successfully!";
}
catch(System.Exception exc)
{return exc.Message;}
}
return "Please select a file to upload!";
}
}
}
请问以上的类文件可以用vb来写吗?功能是不是一样的呢?谢谢.
