Question

我正在尝试打开动态编译的表单，但是没有任何想法如何做到这一点。我可以执行表格所具有的功能，但是如何显示表格我不知道。

我在Form1类中执行测试函数的示例（它只是打开带有单词文本的MessageBox）

using System;
using System.CodeDom.Compiler;
using System.IO;
using Microsoft.CSharp;

namespace myConsoleCompiler
{
    class Program
    {
        static void Main(string[] args)
        {
            using (var foo = new CSharpCodeProvider())
            {
                var parameters = new CompilerParameters
                {
                    GenerateInMemory = true,
                    GenerateExecutable = false
                };

                parameters.ReferencedAssemblies.Add("System.dll");
                parameters.ReferencedAssemblies.Add("System.Core.dll");
                parameters.ReferencedAssemblies.Add("System.Drawing.dll");
                parameters.ReferencedAssemblies.Add("System.Windows.Forms.dll");

                var source = File.ReadAllText("form.txt");
                CompilerResults results = foo.CompileAssemblyFromSource(parameters, source);
                Type type = results.CompiledAssembly.GetType("myForm.Form1");
                object compiledObject = Activator.CreateInstance(type);

                type.GetMethod("test").Invoke(compiledObject, new object[] { });
            }
        }
    }
}

        public void test()
        {
            MessageBox.Show("test");
        }
    }

        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

            this.SuspendLayout();
            //

            this.richTextBox1.Name = "richTextBox1";
            this.richTextBox1.Size = new System.Drawing.Size(260, 204);
            this.richTextBox1.TabIndex = 0;
            this.richTextBox1.Text = "";
            // 
            // button1
            // 
            this.button1.Location = new System.Drawing.Point(12, 222);
            this.button1.Name = "button1";
            this.button1.Size = new System.Drawing.Size(260, 40);
            this.button1.TabIndex = 1;
            this.button1.Text = "button1";
            this.button1.UseVisualStyleBackColor = true;
            //

            this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
            this.ClientSize = new System.Drawing.Size(284, 274);
            this.Controls.Add(this.button1);
            this.Controls.Add(this.richTextBox1);
            this.Name = "Form1";
            this.Text = "Form1";
            this.ResumeLayout(false);

        }

        #endregion

        private System.Windows.Forms.RichTextBox richTextBox1;
        private System.Windows.Forms.Button button1;
    }
}

您可以通过调用Show()或ShowDialog()来显示与正常编译相同的方式（取决于您是否希望将表单显示为模式对话框）：

               Col1      Col2      Col3
XXX   bbb         1         8         1
YYY   bbb         8         7         6
ZZZ   bbb         2         2         4

由于type.GetMethod("Show", new Type[0]).Invoke(compiledObject, new object[] { });方法有多个重载，您需要指定所需版本的参数类型。
