在asp.net后面的代码中访问输入控件的类型文件

Question

在服务器端onClick事件中使用asp.net fileupload字符串。

ASP.Net文件上传控制

<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> 

的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; 
      } 
     } 

也许有一个更好的解决方案，但最终对我有用，因为我想插入数据到数据库中，并使用system.io在单击事件中将新文件写入路径。

Answer 1

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

Answer 2

File1.PostedFile.FileName 

会给你文件名
