您好我想使用c#上传文件,但想要显示如下图片。
经过一些搜索后,我发现无法编辑按钮名称和文本框的设置值。
所以我开发了以下编码。
.ASPX
<input runat="server" id="File1" type="file" style=" visibility:hidden;" />
<input id="Text1" type="text" runat="server" />
<asp:Button ID="Button1" OnClientClick="fireFileClick()" runat="server" Text="Upload" />
的js
function fireFileClick() {
var objfile = document.getElementById("<%= File1.ClientID %>");
objfile.click();
var objTextBox = document.getElementById("<%= Text1.ClientID %>");
objTextBox.value = objfile.value;
}
的.cs
private void SetPicture()
{
string strFileName = System.IO.Path.GetFileName(File1.PostedFile.FileName);
string strExtnt = strFileName.Substring(strFileName.LastIndexOf('.') + 1).ToUpper();
System.Drawing.Image UploadedImage = System.Drawing.Image.FromStream(File1.PostedFile.InputStream);
float UploadedImageWidth = UploadedImage.PhysicalDimension.Width;
float UploadedImageHeight = UploadedImage.PhysicalDimension.Height;
if (UploadedImageWidth < 185 && UploadedImageHeight < 51)
{
}
}
问题在于.CS我没有获取文件名和路径。变量strFileName,strExtnt返回空。有些人指导我。

你可以这样做。
<强> .ASPX 强>:
<input id="File1" type="file" runat="server" style="visibility: hidden"
onchange="this.form.submit();" />
<input id="Button2" type="button" onclick="fireFileClick();" value="Upload" />
<强>的JavaScript 强>:
function fireFileClick() {
document.getElementById("<%= File1.ClientID %>").click();
}
.cs :与您的相同。
注意:随意更改您在JavaScript中提交表单的方式,我只是用最快的方式。表格将在用户选择文件后提交。

基本上使用两个输入控件,隐藏实际的输入上传控件,并将样式应用于非文件上传控件。真棒酱!

使用两个js文件http://the-echoplex.net/demos/upload-file/file-upload.js和http://the-echoplex.net/demos/upload-file/jelly/min.js。并添加file-upload.css文件。您的样本 aspx文件是,
