asp.net - how to convert list to datatable -

-

संभव डुप्लिकेट:

नमस्ते, मैं डेटाटाइप को डेटाटाइप में परिवर्तित करना चाहता हूं। मैंने फ़ंक्शन लिखा 

  स्थिर डेटाटैबल सूचीटोडडेटाबल & lt; T & gt; (IEnumerable & lt; T & gt; सूची) {var dt = new DataTable (); विदेशी मुद्रा (प्रकार की जानकारी में टाइपफ (टी) .GetProperties ()) {dt.Columns.Add (नया DataColumn (info.Name, info.PropertyType)); } Foreach (सूची में var t) {var row = dt.NewRow (); विदेशी मुद्रा (प्रकार की जानकारी में टाइपफ (टी)। गेटप्रॉपर्टीज ()) {पंक्ति [info.Name] = info.GetValue (t, null); } Dt.Rows.Add (पंक्ति); } वापसी डीटी; }

लेकिन यह अपवाद फेंक रहा है "डेटासेट सिस्टम का समर्थन नहीं करता है।" Lll;> "हम इसे कैसे हल कर सकते हैं या कोई अन्य समाधान है

इसे एक प्रयास करें ... 

  // तालिका का निर्माण करते समय प्रकार pt = info.PropertyType; अगर (pt.IsGenericType & amp; amp; pt.GetGenericTypeDefinition () == टाइपफ (Nullable & lt; & gt;)) pt = Nullable.GetUnderlyingType (pt); } Dt.Columns.Add (नया DataColumn (info.Name, pt)); // जब टेबल पंक्ति लोड करना [info.Name] = info.GetValue (टी, रिक्त) ?? DBNull.Value;

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
