मेरे कोड के लिए त्रुटि 

  त्रुटि unassigned स्थानीय वेरिएबल (स्विच) का उपयोग सी # के लिए strFavoriteColor

मेरे कोड: 

  निजी शून्य lstData_SelectedIndexChanged (ऑब्जेक्ट प्रेषक, EventArgs ई) {string strName; स्ट्रिंग strFavoriteColor; StrName = lstData.Items [lstData.SelectedIndex] .ओस्ट्रिंग (); स्विच (strName) {मामला "अमीर": strFavoritecolor = "abi"; टूटना; मामला "महदी": strFavoriteColor = "सबज़"; टूटना; मामले "मीसाम": strFavoriteColor = "Siah"; टूटना; मामले "अमीन": strFavoriteColor = "zard"; टूटना; मामले "रजा": strFavoriteColor = "बाना"; टूटना; } MessageBox.Show (strName + "का पसंदीदा रंग" + strFavoriteColor, "चुनें डेमो");

क्या समस्या हो सकती है?

इसके बजाय

<पूर्व> स्ट्रिंग strFavoriteColor;

लिखें 

  स्ट्रिंग strFavoriteColor = "";

आपने इसे प्रारंभ नहीं किया था और आप अपने स्विच स्टेटमेंट में कोई भी मैच नहीं प्राप्त कर सकते हैं।

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
