C# ExecuteOnQuery（）-at System.RuntimeMethodHandle.InvokeMethod（对象目标、对象[]参数、签名符号、布尔构造函数）

使用SSIS的脚本组件执行C代码时，出现以下错误：

在System.RuntimeMethodHandle.InvokeMethodObject目标处，对象[]参数，签名符号，布尔构造函数 在System.Reflection.RuntimeMethodInfo.UnsafeInvokeInternalObject obj中，对象[]参数，对象[]参数 在System.Reflection.RuntimeMethodInfo.InvokeObject obj中，BindingFlags invokeAttr、Binder Binder、Object[]参数、CultureInfo区域性 在System.RuntimeType.InvokeMemberString名称、BindingFlags BindingFlags、Binder Binder、对象目标、对象[]提供的参数、参数修改器[]修饰符、CultureInfo区域性、字符串[]namedParams 位于Microsoft.SqlServer.Dts.Tasks.ScriptTask.vstatasksscriptingengine.ExecuteScript

在这里，我正在读取一个excel文件，并在文件名上动态创建一个sql server表并加载数据。 在创建表时遇到此错误，尤其是在执行语句myCommand.ExecuteOnQuery时

参考代码：-

SqlConnection myADONETConnection = new SqlConnection();
 myADONETConnection = (SqlConnection)(Dts.Connections["LANDConn"].AcquireConnection(Dts.Transaction) as SqlConnection);
SqlCommand myCommand = new SqlCommand(tableDDL, myADONETConnection);
myCommand.ExecuteNonQuery(); 

我该怎么办？

公用空主机

{ 字符串FolderPath=Dts.Variables[User:：FolderPath].Value.ToString

var directory=newdirectoryInfoFolderPath

FileInfo[]files=directory.GetFiles

字符串fileFullPath=

文件中的foreach FileInfo文件

{

}

请调试并向我们显示您正在发送的sqlcommand。您的错误消息中没有错误。您没有发布足够的信息，任何人都无法帮助您。您好，我已使用上述代码从excel文件读取数据，并从这些excel文件动态创建表。但是，收到提到的错误消息是错误的特别是在myCommand.ExecuteNonQuery；行。请任何人建议任何选项来更正我。。
