Convert from textbox string to double in C# -

इस सवाल का पहले से ही एक उत्तर है: < / P>

  • 5 जवाब

मैं एक सिस्टम कर रहा हूँ सी # पर और सबकुछ ठीक हो रहा है, लेकिन जब मैं एक टेक्स्ट बॉक्स वैल्यू को दोहरा कर बदलना चाहता हूँ, उदाहरण के लिए: जब मैं 123.40 में प्रवेश करता हूँ तो इसे डबल में बदलने का परिणाम 12340 है। यह मेरा कोड है:

<प्री> डबल। पाठ (टीएसटीपी। टेस्ट)

और अगर मैं इसके साथ कोशिश करता हूं: 

  कन्वर्ट। दोहराएं (txtPay.Text)

परिणाम एक जैसा है

ऐसा लगता है कि । आपके लोकेल में दशमलव विभाजक नहीं है - इसके बजाय, यह शायद , है, जिसका अर्थ है कि आपको 123,40 दर्ज करना होगा।

हालांकि, आप एक अपरिवर्तनीय संस्कृति का उपयोग एक डबल पार्स करने के लिए कर सकते हैं जहां । दशमलव विभाजक के रूप में उपयोग किया जाता है। 

  System.Globalization का उपयोग कर; डबल। पेर्स ("4.0", संस्कृति इन्फोक। इन्विरिएन्ट कल्चर);

इसके अलावा, यह अत्यधिक अनुशंसा की जाती है कि आप उपयोगकर्ता इनपुट को मान्य करने और अपवादों से बचने के लिए पार्स या कन्वर्ट के बजाय का उपयोग करें।
