मुझे नीचे वर्णित मिल रहा है

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।

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
