异常“字符串不能有零长度”在对话框初始化组件中

我在同一解决方案中将几个对话框窗体从一个类库移动到另一个类库（拖放）（两者都是 c# 类库）。然后在运行时，我开始在 InitializeComponent 方法中myform.Designer.cs该目标 dll 中移动的和以前存在的表单的行中

this.pictureBox1.Image = global::mydll.Properties.Resources.Webster;

例外情况是：

字符串的长度不能为零。

有时表单会在第一次正确加载，但之后不会。

您是否曾经遇到过将表单从一个项目移动到另一个项目的问题？

我确实更新了所有命名空间以使用目标 dll 命名空间。

--解决

按照 Avi 的指示，我启用了"第一次机会异常"并在下面的程序集解析代码中发现了问题（显然这是试图加载程序集但未能这样做）：

currentDomain.AssemblyResolve += new ResolveEventHandler(currentDomain_AssemblyResolve);

......

    Assembly currentDomain_AssemblyResolve(object sender, ResolveEventArgs args){
        //This handler is called only when the common language runtime tries to bind to the assembly and fails.
        //Retrieve the list of referenced assemblies in an array of AssemblyName.
        Assembly MyAssembly, objExecutingAssemblies;
        string strTempAssmbPath = "";
        objExecutingAssemblies = Assembly.GetExecutingAssembly();
        AssemblyName[] arrReferencedAssmbNames = objExecutingAssemblies.GetReferencedAssemblies();
        //Loop through the array of referenced assembly names.
        foreach (AssemblyName strAssmbName in arrReferencedAssmbNames)
        {
            //Check for the assembly names that have raised the "AssemblyResolve" event.
            if (strAssmbName.FullName.Substring(0, strAssmbName.FullName.IndexOf(",")) == args.Name.Substring(0, args.Name.IndexOf(",")))
            {
                //Build the path of the assembly from where it has to be loaded.
                //The following line is probably the only line of code in this method you may need to modify:
                RegistryKey regkey = Registry.LocalMachine.OpenSubKey(@"Software'ProjectONE'addin");
                strTempAssmbPath = regkey.GetValue("DllLocation").ToString();
                if (strTempAssmbPath.EndsWith("''")) strTempAssmbPath += "''";
                strTempAssmbPath += args.Name.Substring(0, args.Name.IndexOf(",")) + ".dll";
                break;
            }
        }
        //Load the assembly from the specified path.
        MyAssembly = Assembly.LoadFrom(strTempAssmbPath);
        //Return the loaded assembly.
        return MyAssembly;
    }

我刚刚完全删除了"程序集解析"代码，因为我将窗体从一个类库移动到另一个类库的目标是减少我的解决方案 dll 的数量。

我相信这个问题仍然是我的情况所独有的，但有人可能会发现这很有用。

谢谢。
