Hi All, I really need to create something like the following:
Type t = Type.GetType("IEnumerable<" + tableNameAsSingular + ">");
CodeFunction2 finderFunction = (CodeFunction2)entityServiceClass.AddFunction("Get" + table.Name, vsCMFunction.vsCMFunctionFunction, t, -1, vsCMAccess.vsCMAccessPublic, null);
but t is always null, as this code is being generate the tableNameAsSingular type will not exist until just before this CodeFuncation is added. Any help or pointers would be greatfully received. Also if anyone knows where a plethora of EnvDTE code generation knowledge lives I would be sooo greatful! Best Regards, Phill skype: phill.duffy

string returnType = "System.Collections.Generic.IEnumerable<" + tableNameAsSingular + ">"; <br />
CodeFunction2 finderFunction = (CodeFunction2)entityServiceClass.AddFunction("Get" + table.Name, vsCMFunction.vsCMFunctionFunction, returnType, -1, vsCMAccess.vsCMAccessPublic, null);
Why Chao's worked without the full name is of wonder but heck, I am a happy bunny!!!!!!!!!!!!!

I am doubting why you not use the type string directly, the Type parameter is a object type and could receive a string As its value. Like
string t = "IEnumerable<" + tableNameAsSingular + ">";
CodeFunction2 finderFunction = (CodeFunction2)entityServiceClass.AddFunction("Get" + table.Name, vsCMFunction.vsCMFunctionFunction, t, -1, vsCMAccess.vsCMAccessPublic, null);
I think this is perfect.
If I misunderstood you, feel free to let me know
Thanks
Chao | | Chao Kuo Tuesday, October 13, 2009 4:02 AM | Hi Chao, Thank you for your reply, I did have it like you do there, with the string, but I get the following: "IEnumerable<CustomerEntity>' is not a valid identifier" I create these classes in the DSL I am writing: 1: CustomerEntity - This defines Customer properties 2: CustomerEntityService - This has methods for processing CustomerEntities When an item is dropped onto my DSL diagram it creates the files in the users solution, if I could get the 'Dynamic Type' from the CodeClass2 I might be able to use that but so far I have been unable to find out how to do this. I am working with a DSL which means my CodeGenerator class sits in a different assembly/solution as to where this code is being generated. I am able to get IntelliSense on the CustomerEntity class, if I go in and manually type into the CustomerEntityService.cs Regards, Phill
BDC Meta Man Web Edition - Out Now | | Phill Duffy [MCTS] Tuesday, October 13, 2009 8:52 AM | Hi, Phill Thanks for your following up. The Type parameter does not receive a Type object, and it is not right for you to get type through
Type t = Type.GetType("IEnumerable<" + tableNameAsSingular + ">");
Expression. If you want to use IEnumerable<CustomerEntity> as your return type, I think the most appropriate method is use string as the parameter. I have test the expression, it does not throw any errors on my side if the CustomerEntity could be recognized. And could you post the fragment here in order for me to find the error. Thanks Chao | | Chao Kuo Tuesday, October 13, 2009 10:14 AM | Hi Chao, Thanks again for your reply:
public void AddFinderMethod()
{
string t = "IEnumerable<" + tableNameAsSingular + ">";
CodeFunction2 finderFunction = (CodeFunction2)entityServiceClass.AddFunction("Get" + table.Name, vsCMFunction.vsCMFunctionFunction, t, -1, vsCMAccess.vsCMAccessPublic, null);
// Code here remove as it does not get this far yet.
}

case EntityClassType.EntityService:

className = tableNameAsSingular + "Service";
break;
}
ProjectItems projectItems;
ProjectItem projectItem;
String csItemTemplatePath;
Solution2 soln;
soln = (Solution2)EnvDte.Solution;
projectItems = EnvDte.ActiveDocument.ProjectItem.ProjectItems;
csItemTemplatePath = soln.GetProjectItemTemplate("CodeFile", "CSharp");

switch (entityClassType)

case EntityClassType.EntityService:
fcm.AddImport("System.Linq");
fcm.AddImport("System.Collections.Generic");
break;
}
EnvDTE.CodeNamespace projectCodeNamespace;
try
{
// Add a namespace.
projectCodeNamespace = fcm.AddNamespace(projectNamespace, -1);
if (projectCodeNamespace != null)
{
// Add a class to the namespace.
return (CodeClass2)projectCodeNamespace.AddClass(className, -1, null, null, vsCMAccess.vsCMAccessPublic);
}
}
catch (Exception ex)
{
// throw ex;
}
return null;
}
entityServiceClass is a CodeClass2 object , tableNameAsSingular is the name of the class and it is public too. Do I need to save the Entity Class before I can do this?
BDC Meta Man Web Edition - Out Now | | Phill Duffy [MCTS] Tuesday, October 13, 2009 11:41 AM | I should add if I do:
public void AddFinderMethod()
{
string t = tableNameAsSingular;
CodeFunction2 finderFunction = (CodeFunction2)entityServiceClass.AddFunction("Get" + table.Name, vsCMFunction.vsCMFunctionFunction, t, -1, vsCMAccess.vsCMAccessPublic, null);
// Code here remove as it does not get this far yet.
}
it does work

I have tried my best, but I am still not able to reproduce this error. I use almost the same code with you, but IEnumerable<ProductEntity> is a right identifier on my side. Really sorry for that.
Thanks
Chao | | Chao Kuo Wednesday, October 14, 2009 5:06 AM | D'oh. I was hoping for some wonderful news :) I really appreciate you trying to replicate and solve my issue. I really need this fixed so I will post here if\when I manage it. Best Regards, Phill

I am sorry I am falling asleep that time yesterday because that time was night in far east asian.
Thank goodness, you got it worked. And You are so kind to share your answer with others.
I spent a whole morning to reproduce your errors, but I did not work out. So I have to give up. It is so strange that I work it out without full work.
Thanks
