Я сталкиваюсь с этой ошибкой каждый раз, когда хочу записать файл в папку.Доступ к пути 'xxxxxxxxx' отрицается
Вот мой код:
protected void ListAttachments(List<MessagePart> msgParts)
{
bool attachmentsFound = false;
StringBuilder b = new StringBuilder();
b.Append("<ol>");
foreach (MessagePart p in msgParts)
{
string contentType = p.Headers["Content-Type"];
string contentDisposition = p.Headers["Content-Disposition"];
Match m;
if (contentDisposition != null)
{
m = FilenameRegex.Match(contentDisposition);
if (m.Success)
{
attachmentsFound = true;
b.Append("<li><a href='Handler.ashx?fileName=" + m.Groups["filename"].Value + "'>").Append(m.Groups["filename"].Value).Append("</a></li>");
Response.AppendHeader("content-disposition", "attachment; filename=" + m.Groups["filename"].Value);
Response.ContentType = "application/octet-stream";
//Error Occurs
Response.TransmitFile(Server.MapPath(@"~/Files"));
Response.End();
}
}
else if (contentType != null)
{
m = NameRegex.Match(contentType);
if (m.Success)
{
attachmentsFound = true;
b.Append("<li><a href='Handler.ashx?fileName="+m.Groups["filename"].Value+"'>").Append(m.Groups["filename"].Value).Append("</a></li>");
}
}
}
b.Append("</ol>");
if (attachmentsFound)
AttachmentsLiteral.Text = b.ToString();
else
AttachementsRow.Visible = false;
}
Здесь ошибка возникает, как Access to the path 'F:\Gmail\Files' is denied.
Это информация об ошибке:
Server Error in '/Gmail' Application.
Access to the path 'F:\Gmail\Files' is denied.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.UnauthorizedAccessException: Access to the path 'F:\Gmail\Files' is denied.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.
