SSIS Script Task C# Only assignment and new object expressions can be used 错误

Question

我在 SSIS 中使用 C# 脚本任务来检查文件的文件大小并与名为 FileFoundSize 的变量进行比较。这是我的代码：

    public void Main()
    {
        string fullPath = Path.Combine(Dts.Variables["$Project::ValidationImport"].Value.ToString(), Dts.Variables["User::zipFileName"].Value.ToString());
        var fileInfo = new FileInfo(fullPath);

        if (fileInfo.Exists)
        {
            fileInfo.Length > Dts.Variables["User::FileFoundSize"];
            Dts.TaskResult = (int)ScriptResults.Success;
        }
        else
        {
            // file could not be found     
            Dts.TaskResult = (int)ScriptResults.Failure;
        }
    }

然而，编辑一直强调这一行：

fileInfo.Length > Dts.Variables["User::FileFoundSize"];

并指出这个错误：

我错过了什么？

尝试使用以下代码，您错过了变量

的值属性

if (fileInfo.Exists)
{
        if(fileInfo.Length > Convert.ToInt32(Dts.Variables["User::FileFoundSize"].Value.ToString()))
           Dts.TaskResult = (int)ScriptResults.Success;
        else
           Dts.TaskResult = (int)ScriptResults.Failure;
}
else
{
        Dts.TaskResult = (int)ScriptResults.Failure;
}
