使用asp.net将大文件上传到sharepoint文档库 [英] Upload large file into sharepoint document library using asp.net
问题描述
我正在将文件从asp.net应用程序上传到sharepoint文档库.
最多可以上传50MB的文件.当我上传超过50MB的文件时，不允许.
我的IIS是IIS 6.0.
该怎么做.
在WEB应用程序常规设置下的sharepoint文档库中，我已经设置了
文件上传大小为200MB，但不起作用.
和web.config我添加了这个:
< httpruntime executetimeout ="3600">
maxRequestLength ="200000"
useFullyQualifiedRedirectUrl ="false"
minFreeThreads ="8"
minLocalRequestFreeThreads ="4"
appRequestQueueLimit ="100"/>
这是我的代码:
--------------------
受保护的无效btnUpload_Click(对象发送者，EventArgs e)
{
字符串uploadFilePath = @"E:\ New Folder \";
字符串sharePointListPath =
"sharepointserverpath";
如果(FileUpload1.HasFile)
试试
{
FileUpload1.SaveAs(
uploadFilePath + FileUpload1.FileName);
Label1.Text =文件名:" +
FileUpload1.PostedFile.FileName +"
" +
FileUpload1.PostedFile.ContentLength +"bytes
" +
内容类型:" +
FileUpload1.PostedFile.ContentType;
UploadFileToSharePoint(
UploadedFilePath + FileUpload1.FileName，
sharePointListPath + FileUpload1.FileName);
}
catch(ex ex例外)
{
Label1.Text ="ERROR:" + ex.Message.ToString();
}
其他
{
Label1.Text =您尚未指定文件.";
}
}
受保护的void UploadFileToSharePoint(字符串UploadedFilePath，字符串SharePointPath)
{
Web响应；响应=空；
试试
{
//创建一个PUT Web请求以上传文件.
WebRequest请求= WebRequest.Create(SharePointPath);
request.Credentials = CredentialCache.DefaultCredentials;
request.Method ="PUT";
//分配1 KB的缓冲区以传输文件内容.
//您可以根据需要调整缓冲区大小，具体取决于
//正在上传的文件的数量和大小.
字节[]缓冲区=新字节[1024];
//将本地文件的内容写入
//请求流.
使用(Stream stream = request.GetRequestStream())
使用(FileStream fsWorkbook = File.Open(UploadedFilePath，
FileMode.Open，FileAccess.Read))
{
int i = fsWorkbook.Read(buffer，0，buffer.Length);
而(i> 0)
{
stream.Write(buffer，0，i);
i = fsWorkbook.Read(buffer，0，buffer.Length);
}
}
//发出PUT请求.
响应= request.GetResponse();
}
catch(ex ex例外)
{
扔前;
}
终于
{
response.Close();
}
}

// Create a PUT Web request to upload the file.
WebRequest request = WebRequest.Create(SharePointPath);
request.Credentials = CredentialCache.DefaultCredentials;
request.Method = "PUT";
// Allocate a 1 KB buffer to transfer the file contents.
// You can adjust the buffer size as needed, depending on
// the number and size of files being uploaded.
byte[] buffer = new byte[1024];
// Write the contents of the local file to the
// request stream.
using (Stream stream = request.GetRequestStream())
using (FileStream fsWorkbook = File.Open(UploadedFilePath,
FileMode.Open, FileAccess.Read))
{
int i = fsWorkbook.Read(buffer, 0, buffer.Length);
while (i > 0)
{
stream.Write(buffer, 0, i);
i = fsWorkbook.Read(buffer, 0, buffer.Length);
}
}
// Make the PUT request.
response = request.GetResponse();
}
catch (Exception ex)
{
throw ex;
}
finally
{
response.Close();
}
}
推荐答案
Generally, the uploading limit of ASP.NET FileUploader is 4MB. But you can increase the limit of length of uploaded file by using the following code into your web.config file in your website.
<httpruntime maxrequestlength="20480" executiontimeout="600">
</httpruntime>
