在asp.net背后的代码中访问类型文件的输入控件

Question

在服务器端 onClick 事件中使用 asp.net 文件上传字符串。

ASP.Net 文件上传控件

<asp:FileUpload ID="btnFileUpload" runat="server" Width="0px" onchange="this.form.lblUploadStatus.value=GetFileName(this.value);"/>
<asp:TextBox ID="txtUploadStatus" runat="server" Width="680px"></asp:TextBox>

Javascript

<script type="text/javascript">

function GetFileName(val) {
    var i = val.lastIndexOf("\\");
    $get('<%= txtUploadStatus.ClientID %>').value = val;
    return true;
}

</script>

.net

using (SqlConnection dbConnection = new SqlConnection(CKS_app_settings.sql_conn_string_db))
        {
            try
            {
                dbConnection.Open();
                SqlCommand command = new SqlCommand(sSQL, dbConnection);
                //command.Transaction = tn;
                command.CommandText = sSQL;
                command.CommandType = CommandType.StoredProcedure;
                command.CommandTimeout = 1024;

                // Split entire file path to grab filename
                string[] split = txtUploadStatus.Text.Split(new char[] { '\\' });
                string fileName = split[06];

                command.Parameters.AddWithValue("@p_filename", fileName);
                command.Parameters.AddWithValue("@p_url", txtUrl.Text);
                command.Parameters.AddWithValue("@p_Title", txtImgTitle.Text);
                command.Parameters.AddWithValue("@p_alt_text", txtAlt.Text);
                int rowsAffected = command.ExecuteNonQuery();
            }
            catch (SqlException ex)
            {
               // throw ex;

                //If it failed for whatever reason, rollback the //transaction
                //tn.Rollback();                          
                //No need to throw because we are at a top level call and //nothing is handling exceptions
                result = ex.InnerException.Message;
            }
        }

也许有更好的解决方案，但这最终对我有用，因为我想插入数据进入数据库并使用 system.io 通过一键事件将新文件写入路径。

Answer 1

HttpPostedFile file = File1.PostedFile;
string sName = file.FileName; // Contains file name

Answer 2

File1.PostedFile.FileName 

将为您提供文件名，

请按照其示例
