動態編譯C#文本程序

平時我們都是使用開發環境將程序文件編譯好,產生我們需要的程序,那可不可以實現將文本程序代碼動態編譯,以達到程序效果預覽或者簡單開發環境搭建的目的呢?

 

以下的程序可以給你答案:

 

 

 using System; using System.Windows.Forms; namespace CompileDynamic { static class Program { [STAThread] static void Main() { string sourceCode = "using System; " + "using System.Windows.Forms; " + "class program " + "{ " + " static void Main() " + " { " + " Application.EnableVisualStyles(); " + " Application.SetCompatibleTextRenderingDefault(false); " + " Application.Run(new Form()); " + " } " + "} "; DynamicCompile(sourceCode, null, "exe", Application.StartupPath + "//text.exe", true, true); } /// <summary> /// 動態編譯c#文本程序方法 /// </summary> /// <param name="sourceCode">源代碼文本</param> /// <param name="assemblyFileNames">所引用的程序集組件,如System.dll</param> /// <param name="outputType">輸出的類型,可以爲exe,winexe,library,module</param> /// <param name="outputName">程序組件生成的全路徑</param> /// <param name="showError">是否顯示編譯的錯誤</param> /// <param name="startApp">編譯成功是否啓動程序</param> public static void DynamicCompile(string sourceCode, string[] assemblyFileNames, string outputType, string outputName, bool showError, bool startApp) { System.CodeDom.Compiler.CodeDomProvider cdp = System.CodeDom.Compiler.CodeDomProvider.CreateProvider("C#"); //config compile parameters if (assemblyFileNames == null || assemblyFileNames.Length == 0) assemblyFileNames = new string[] { "System.dll", "dll", "System.Drawing.dll", "mscorlib.dll" }; System.CodeDom.Compiler.CompilerParameters cp = new System.CodeDom.Compiler.CompilerParameters(assemblyFileNames); cp.GenerateInMemory = true; switch (outputType) { case "exe": cp.CompilerOptions = "/t:exe"; break; case "winexe": cp.CompilerOptions = "/t:winexe"; break; case "library": cp.CompilerOptions = "/t:library"; break; case "module": cp.CompilerOptions = "/t:module"; break; default: cp.CompilerOptions = "/t:exe"; break; } //Config output fullname if (string.IsNullOrEmpty(outputName)) outputName = System.Environment.SpecialFolder.MyDocuments + "//myapp.exe"; cp.GenerateExecutable = true; cp.OutputAssembly = outputName; //List errors System.CodeDom.Compiler.CompilerResults cr = cdp.CompileAssemblyFromSource(cp, sourceCode); if (showError && cr.Errors.HasErrors) { string errMsg = ""; for (int i = 0; i < cr.Errors.Count; i++) errMsg += cr.Errors[i].Line + ":" + cr.Errors[i].ErrorText + "/r/n"; MessageBox.Show(errMsg, "Error", MessageBoxButtons.OK, System.Windows.Forms.MessageBoxIcon.Error); } //Indicate whether to start compiled assembly if (startApp) { System.Reflection.Assembly ass = cr.CompiledAssembly; System.Threading.Thread thread = new System.Threading.Thread(delegate() { foreach (System.Type type in ass.GetTypes()) { //之所以不直接使用EntryPoint屬性，是因爲如果編譯成dll，將返回null System.Reflection.MethodInfo mi = type.GetMethod("Main", System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Static); if (mi != null) { try { mi.Invoke(null, null); break; } catch (System.Exception ex) { MessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error); } } } }); thread.SetApartmentState(System.Threading.ApartmentState.STA); thread.Start(); } } } }
