Question

  

System.Security.SecurityException：请求类型为“ System.Security.Permissions.FileIOPermission，mscorlib，Version = 2.0.0.0，Culture = neutral，PublicKeyToken = b77a5c561934e089”的权限失败。

在将多个图像压缩为zip时，我得到了以上提示...

我的代码只能在本地运行，而不能实时运行。

我在web.config行下面尝试过。

<trust level="Full" /> 

但问题没有解决。

Web.Config

<system.web>
<trust level="Full" />
<customErrors mode="Off"/>
<!--

        symbols into the compiled page. Because this 
        affects performance, set this value to true only 
        during development.
    -->
    <compilation debug="true" />
    <!--

    <!--

    </customErrors>
    -->
</system.web>

按钮代码：

protected void DownloadFiles(object sender, EventArgs e)
{
    String StrSql = "";
    OleDbConnection Cn = new OleDbConnection(System.Configuration.ConfigurationManager.AppSettings["con"].ToString());

    StrSql = "select Convert(nvarchar(50),WdPrefix)+''+Convert(nvarchar(50),WdCertNo)+''+Convert(nvarchar(50),WdCertChr) as CertificateNo from WorksheetDetails  where WdRefId='" + ClsBackOffice.Decrypt(spnWmId .InnerHtml)+ "'";
    OleDbDataAdapter Da = new OleDbDataAdapter(StrSql, Cn);
    DataSet Ds = new DataSet();
    DataRow R;
    Da.Fill(Ds, "DATA");
    ZipFile zip = new ZipFile();

    zip.AlternateEncodingUsage = ZipOption.AsNecessary;
    zip.AddDirectoryByName("Files");

    for (Int16 i = 0; i < Ds.Tables["DATA"].Rows.Count; i++)
    {

        R = Ds.Tables["DATA"].Rows[i];

        String mFileName=R["CertificateNo"].ToString();
        String filePath = AppDomain.CurrentDomain.BaseDirectory.ToString() + @"TempFiles\" + mFileName + "-Print.jpg";

        zip.AddFile(filePath, "Files");
    }

        Response.Clear();
        Response.BufferOutput = false;
        string zipName = String.Format("Zip_" + spnJobCardNo.InnerHtml + ".zip");
        Response.ContentType = "application/zip";
        Response.AddHeader("content-disposition", "attachment; filename=" + zipName);
        zip.Save(Response.OutputStream);
        Response.End();

}

此行发生错误：

zip.AddFile(filePath, "Files");
