c# - Type 'MyClass' cannot inherit from a type that is not marked with DataContractAttribute or SerializableAttribute. Consider marking the base type -

i error message when try serialize entity derives tableentity:

type 'myclass' cannot inherit type not marked datacontractattribute or serializableattribute. consider marking base type 'microsoft.windowsazure.storage.table.tableentity' datacontractattribute or serializableattribute, or removing them derived type.

the error message pretty clear what's going wrong.

so question is, how can work around datacontractattribute not being decorated in tableentity class?

code:

[datacontract] public class myclass : myowntableentity  {     [datamember]     public string name { get; set; }      [datamember]     public string email { get; set; } }

i need serialize myclass byte[] , save table storage.

public class myclassasbytearray : myowntableentity  {    public byte[] somebytearray { get; set; } }

if has suggestion on how serialize byte[], please let me know.

[edit]

i decided create own serializable tableentity:

[datacontract] public class myowntableentity : itableentity {     private tableentity te = new tableentity();      public myowntableentity ()     {     }      public myowntableentity (string partitionkey, string rowkey)     {         this.partitionkey = partitionkey;         this.rowkey = rowkey;     }      public string partitionkey { get; set; }      public string rowkey { get; set; }      public datetimeoffset timestamp { get; set; }      public string etag { get; set; }      public virtual void readentity(idictionary<string, entityproperty> properties, operationcontext operationcontext)     {         te.readentity(properties, operationcontext);     }      public virtual idictionary<string, entityproperty> writeentity(operationcontext operationcontext)     {         return te.writeentity(operationcontext);     } }

and derive class, fails writing properties of myclass , myclassasbytearray storage table. , that's because created new object of tableentity.

how can forward parameters passed readentity , writeentity in myowntableentity readentity , writeentity methods in actual tableentity class?

microsoft wrote code, i'd prevent reinventing wheel here.

edit see tableentity.cs

went mssql , dropped azure table storage solution. because has many limitations.

python - TypeError: can only concatenate tuple (not "float") to tuple -

-
i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
