CodeDom generic type constraint

阅读更多关于 CodeDom generic type constraint

问题 Is there a way to generate a class constraint with CodeDom. Because when I use something like var method = new CodeMemberMethod(); var genericParam = new CodeTypeParameter("InterfaceType"); genericParam.Constraints.Add("class"); method.TypeParameters.Add(genericParam); the generated code is like private InterfaceType GetImpl<InterfaceType>() where InterfaceType : @class { } The best workaround i found is to use a leading whitespace before the class genericParam.Constraints.Add(" class"); But

Create an .EXE from an .EXE

阅读更多关于 Create an .EXE from an .EXE

So what I want to do is create an executable in a program in vb. What I mean by this is that there is a program that can output a .EXE. What I try to do is to create a program that can output a smaller program that runs predefined commands. All I know is that it is somehow possible with a STUB. That you open the STUB and add extra code to it and save it again as an .EXE. You can use compiler services to create EXE at run time.

Parsing C# source code

问题 I'm trying to parse a simple.cs source file using the following code: CodeDomProvider provider = CodeDomProvider.CreateProvider("CSharp"); var compileUnit = provider.Parse(File.OpenText(filename)); This gives me a NotImplementedException: "This CodeDomProvider does not support this method" Is it true that .NET does not provide an implemenation for parsing C# code? Or am I just using this class the wrong way? Edit: The reason for doing this is that I want to toy around with some methods for

C# CodeDom Automatic Property

阅读更多关于 C# CodeDom Automatic Property

问题 I have a property created with CodeDom. How can I set it to being an automatic property instead of adding CodeFieldReferenceExpressions against a private member? 回答1: IIRC, CodeDom simply doesn't have a way of expressing this. Automatically implemented properties are just compiler sugar, but since it doesn't map (cleanly) to all languages, it doesn't fit cleanly into CodeDom (besides, CodeDom would have needed an update). 回答2: Yes you can. You can use CodeSnippetTypeMember class for that

Dynamically execute string as code in C#

阅读更多关于 Dynamically execute string as code in C#

问题 I need to convert string to executable code. The string is in foreach statement. foreach (InsuredItem _i in p.InsuredItems) { string formula = "(_i.PremiumRate/100)*SumAssured"; _i.Premium = (Execute formula); } The formula is loaded from setup. this is just a demonstration. I need to execute the string in foreach loop. Thanks. 回答1: Assuming that your formula is valid C# code and that it uses a known set of local variables (so that you can create a "globals" type containing all of them), you

how to create an interface method with CodeDom

阅读更多关于 how to create an interface method with CodeDom

问题 I am using CodeDom to generate my WCF service interfaces and implementation files. I cannot find any options on CodeMemberMethod that will allow me to generate an interface method. If I use MemberAttributes.Abstract I am almost there but it includes the abstract keyword which is invalid for an interface. Does anyone know the correct syntax to generate the method? Here is the code I have developed to generate the interface file: private void CreateServiceContractFile(Type entity, BoElement bo,

Finalizer with CodeDom?

阅读更多关于 Finalizer with CodeDom?

问题 Is it possible to add a Finalizer to a CodeDom generated class (other than using CodeSnippetTypeMember)? I couldn't find any information about it on MSDN. 回答1: This was a known bug in .NET Framework and was reported some time back at http://lab.msdn.microsoft.com/ProductFeedback/viewFeedback.aspx?feedbackId=FDBK48431 But the link above is currently not working.

Should Type.GetType(string) be aware of dynamically generated types?

阅读更多关于 Should Type.GetType(string) be aware of dynamically generated types?

问题 I have an app which creates some code using CodeDom compiler. I can see that the generated assembly is in memory. But when I call Type.GetType(typeName), it returns null. I find this a little bit confusing. What am I doing wrong? static void Main(string[] args) { // FYI: Code is some dummy class with only 1 instance method. string code = System.IO.File.ReadAllText("CodeToCompile.cs.txt"); string errors = null; Assembly asm = DynamicCompiler.Compile(code, generateInMemory: true,
