求助：用 C#调用第三方控件 ocx，报错！

平常用 python。因为需要调用第三方控件的方法，摸索着使用 c#，网上关于 ocx 控件的教程很少，举步维艰。希望各位大佬能指点下问题。 C#小白，轻喷谢谢！！！

代码：

using System; using System.Collections.Generic; using System.ComponentModel; using System.Drawing; using System.Data; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; using AxXX; namespace WindowsFormsControlLibrary2 { public partial class UserControl1: UserControl { public UserControl1() { InitializeComponent(); } private void UserControl1_Load(object sender, EventArgs e) { AxXX xx = new AxXX(); ((System.ComponentModel.ISupportInitialize)(xx)).BeginInit(); this.Controls.Add(xx); ((System.ComponentModel.ISupportInitialize)(xx)).EndInit(); xx.AddImage("168", "123", 1, 90); } } } 

异常：

System.BadImageFormatException HResult=0x8007000B Message=未能加载文件或程序集“file:///C:\Users\aaronhua\Desktop\dllproject\WindowsFormsControlLibrary2\WindowsFormsControlLibrary2\obj\x86\Debug\WindowsFormsControlLibrary2.dll”或它的某一个依赖项。试图加载格式不正确的程序。 Source=mscorlib StackTrace: at System.Reflection.RuntimeAssembly._nLoad(AssemblyName fileName, String codeBase, Evidence assemblySecurity, RuntimeAssembly locationHint, StackCrawlMark& stackMark, IntPtr pPrivHostBinder, Boolean throwOnFileNotFound, Boolean forIntrospection, Boolean suppressSecurityChecks)
