尝试上传文件时出错输入不是有效的 Base-64 字符串，因为它包含非 base 64 字符、两个以上的填充字符或填充字符中的非法字符。我的分配数据库属性>> FileLocation 是一个 varBinary(MAX) ，我做错了哪一部分？
控制器
[HttpPost]
public ActionResult Create(Assignment assignment)
{
if (Request.Files != null && Request.Files.Count == 1)
{
var file = Request.Files[0];
if (file != null && file.ContentLength > 0)
{
var content = new byte[file.ContentLength];
file.InputStream.Read(content, 0, file.ContentLength);
assignment.FileLocation = content;
// the rest of your db code here
}
}
assignment.SubmissionDate = DateTime.Now;
db.Assignments.Add(assignment);
db.SaveChanges();
return RedirectToAction("Index");
}
看法
<% using (Html.BeginForm("Create", "Assignment", FormMethod.Post, new { enctype = "multipart/form-data" }))
{ %>
<%: Html.ValidationSummary(true) %>
...........
<div class="editor-label">
<%: Html.LabelFor(model => model.FileLocation) %>
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.FileLocation, new { type="file"})%>
<%: Html.ValidationMessageFor(model => model.FileLocation) %>
</div>
......
