格式化字符串文字

Question

我想格式化一個字符串值，其格式爲first letter它的Uppercase。
e.g：

string.Format("{0}", "myName"); //Output must be : "MyName" 

我該怎麼辦呢？

Answer 1

請檢查您的案例的MSDN，請參閱TextInfo.ToTitleCase Method。

string myString = "wAr aNd pEaCe";   
TextInfo myTI = new CultureInfo("en-US", false).TextInfo; 
Console.WriteLine("\"{0}\" to titlecase: {1}", myString, myTI.ToTitleCase(myString)); 

Answer 2

嘗試

string test = "myname"; 
string formatted = System.Globalization.CultureInfo 
         .CurrentUICulture.TextInfo.ToTitleCase(test); 

Answer 3

如果你只想首字母大寫，也許：

string s = string.Format("{0}", char.ToUpper(myname[0]) + myname.Substring(1)); 

否則，要爲每個字也許用TextInfo.ToTitleCase？

string s = string.Format("{0}", 
    CultureInfo.CurrentCulture.TextInfo.ToTitleCase(myname)); 

Answer 4

string input = "myname"; 
var charArray = input.ToArray(); 
charArray[0] = char.ToUpper(charArray[0]); 

string result = new string(charArray); 

Answer 5

CultureInfo cultureInfo = Thread.CurrentThread.CurrentCulture; 
TextInfo textInfo = cultureInfo.TextInfo; 

Console.WriteLine("{0}", textInfo.ToTitleCase(myname));
