我想在webapplication中获取sharepoint文档。这是我的代码。
try
{
string sharePointURL = "http://<ipAddress>:<port>/<websiteName>/default.aspx";
SPSite site = new SPSite(sharePointURL); //Error on this line.....
SPWeb web = site.OpenWeb();
web.AllowUnsafeUpdates = true;
string strContentType = "";
// docLib is the name of document library
SPFolder folder = web.GetFolder("docLib");
SPFileCollection files = folder.Files;
string fileName = "temp.xls";
//"docLib" is name of document library and testFile.doc is the name of file
string url = sharePointURL + "/" + "docLib" + "/" + fileName;
SPFile tempFile = web.GetFile(url);
//Get the extension of File.
string[] fext = fileName.Split('.');
byte[] obj = (byte[])tempFile.OpenBinary();
// Get the extension of File to determine the file type
string casestring = "";
if (fext.Length > 1)
{
casestring = fext[fext.Length - 1];
}
//set the content type of file according to extension
switch (casestring)
{
case "txt":
strContentType = "text/plain";
break;
case "htm": strContentType = "text/html";
break;
case "html": strContentType = "text/html";
break;
case "rtf": strContentType = "text/richtext";
break;
case "jpg": strContentType = "image/jpeg";
break;
case "jpeg": strContentType = "image/jpeg";
break;
case "gif": strContentType = "image/gif";
break;
case "bmp": strContentType = "image/bmp";
break;
case "mpg": strContentType = "video/mpeg";
break;
case "mpeg": strContentType = "video/mpeg";
break;
case "avi": strContentType = "video/avi";
break;
case "pdf": strContentType = "application/pdf";
break;
case "doc": strContentType = "application/msword";
break;
case "dot": strContentType = "application/msword";
break;
case "csv": strContentType = "application/vnd.msexcel";
break;
case ".xls": strContentType = "application/vnd.msexcel";
break;
case ".xlt": strContentType = "application/vnd.msexcel";
break;
default: strContentType = "application/octet-stream";
break;
}
Response.ClearContent();
Response.ClearHeaders();
Response.AppendHeader("Content-Disposition",
"attachment; filename= " + fileName);
Response.ContentType = strContentType;
//Check that the client is connected and has
//not closed the connection after the request
if (Response.IsClientConnected)
Response.BinaryWrite(obj);
Response.Flush();
Response.Close();
}
catch (Exception ex)
{
string exMessage = ex.Message;
}
我在这一行上收到错误：
SPSite site = new SPSite(sharePointURL);
错误信息是：
“无法找到[URL]上的Web应用程序。验证您是否正确输入了URL。如果URL应该提供现有内容，系统管理员可能需要添加新的请求URL映射到目标应用程序。”< / p>
请告诉我如何解决。
感谢。

尝试此代码段（根据您的情况调整）：
using Microsoft.SharePoint;
using Microsoft.SharePoint.Utilities;
using Microsoft.SharePoint.WebPartPages;
using Microsoft.SharePoint.WebControls;
try
{
int flag=0;
SPSite site = new SPSite(sharePointURL);
SPWeb web = site.OpenWeb();
web.AllowUnsafeUpdates=true;
string strContentType="";
// docLib is the name of document library
SPFolder folder = web.GetFolder("docLib");
SPFileCollection files=folder.Files;
//"docLib" is name of document library and testFile.doc is the name of file
string url=sharePointURL+"/"+"docLib"+"/"+"testFile.doc"
SPFile tempFile = web.GetFile(url);
//Get the extension of File.
string []fext=this.filename[0].Split('.');
byte []obj=(byte[])tempFile.OpenBinary();
// Get the extension of File to determine the file type
string casestring="";
if(fext.Length>1)
{
casestring= fext[fext.Length-1];
}
//set the content type of file according to extension
switch(casestring)
{
