sql - How to insert NULL value in image column using C# code -


मेरे पास निम्न कोड है 

  cmd पैरामीटर। AddWithValue ( "@ पासवर्ड", (string.IsNullOrEmpty (member.Password)) (वस्तु) DBNull.Value: member.Password); cmd.Parameters.AddWithValue ( "@ छवि", (member.Image == नल) (वस्तु) SqlDbType.Image: member.Image);   
 छवि स्तंभ के लिए शून्य मान जोड़ने में असमर्थ  
 मैं इस त्रुटि मिलती है।  
 
 ओपेरैंड प्रकार संघर्ष: पूर्णांक के साथ असंगत है छवि    
 
 
 यहां आपको: आप गुजर रहे हैं  SqlDbType.Image  (अधिक सामान्यतः  7  के रूप में जाना जाता है) जब आप गुजर जाना चाहिए  अशक्त :  
  cmd.Parameters.AddWithValue ( "@ छवि ", (Member.image == नल)? (वस्तु) DBNull.Value: member.Image);   
 यदि आप स्पष्ट रूप से डेटा प्रकार को निर्दिष्ट करना चाहते हैं, तो अलग से करें; उदाहरण के लिए:  
  cmd.Parameters.AddWithValue ( "@ छवि", (member.Image == नल) (वस्तु) DBNull.Value: member.Image) .SqlDbType = SqlDbType.Image ;

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea.
