Question

我在Visual Studio 2012中开发了一个Windows应用程序，其目标框架为.NET 4.我将其部署在Windows XP SP2计算机中。它曾经工作正常，但现在重新安装Windows XP，应用程序无法正常工作。我在XP中安装了.NET 4框架，但它显示以下错误（来自事件查看器）：

Application: SGate.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.Runtime.InteropServices.COMException
Stack:
   at System.RuntimeTypeHandle.CreateInstance(System.RuntimeType, Boolean, Boolean, Boolean ByRef, System.RuntimeMethodHandleInternal ByRef, Boolean ByRef)
   at System.RuntimeType.CreateInstanceSlow(Boolean, Boolean, Boolean)
   at System.RuntimeType.CreateInstanceDefaultCtor(Boolean, Boolean, Boolean, Boolean)
   at System.Activator.CreateInstance(System.Type, Boolean)
   at SGate.Gate..ctor()
   at SGate.Program.Main()

我搜索了解决方案，我认为异常意味着“从COM方法调用返回无法识别的HRESULT时引发的异常。”但这没有用。有谁知道导致这个错误的原因是什么？

Program.Main（）：

static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Gate());
        }
    }

Gate ctr（）和相关函数：

public Gate()
        {
            InitializeComponent();
            ClearForm();           
        }

private void ClearForm()
        {
            try
            {
                leaveApply = new EmployeeLeaveApplyBO();
                CurrentPageIndex = 1;
                dataGridView1.DataSource = null;
                lblFromDate.Text = "";
                lblLeaveReason.Text = "";
                lblLeavType.Text = "";
                lblName.Text = "";
                lblEmpCode.Text = "";
                lblThumbID.Text = "";
                lblToDate.Text = "";
                lblStatus.Text = "STATUS";
                lblStatus.ForeColor = Color.Black;
                groupBox3.BackColor = System.Drawing.Color.FromArgb(((int)(((byte)(224)))), ((int)(((byte)(224)))), ((int)(((byte)(224)))));
                groupBox1.BackColor = System.Drawing.Color.FromArgb(((int)(((byte)(224)))), ((int)(((byte)(224)))), ((int)(((byte)(224)))));
            }
            catch (Exception e)
            {
                LogUtil.LogError(e.ToString());
            }
        }

Answer 1

尝试调试导致此错误的原因。抛出异常时尝试断开。

步骤： - 转到Debug＆gt;例外...并使用Find ...选项查找System.Runtime.InteropServices.COMException。勾选选项以在抛出时中断，然后调试应用程序。

你应该能够找到问题所在。

如果您不确定究竟是什么导致

，您可以尝试这些

1.Try running visual studio or application as "Run as administrator".
2.Check which platform did you set during build ("AnyCPU, x86, x64")

希望这有帮助，
