c# - 如何将字符串中所有单词的第一个字母大写？

Question

首先，我所有的城市都以大写形式返回，所以我将它们切换为小写。我怎样才能让首字母大写呢？感谢您的帮助!

List<string> cities = new List<string>();

foreach (DataRow row in dt.Rows)
{
    cities.Add(row[0].ToString().ToLower());

    **ADDED THIS BUT NOTHING HAPPENED**
     CultureInfo.CurrentCulture.TextInfo.ToTitleCase(row[0] as string);
}

return cities;

Answer 1

使用 TextInfo.ToTitleCase方法:

System.Globalization.TextInfo.ToTitleCase();

来自 MSDN 示例的一些内容，经过修改以与 OP 的代码一起使用:

// Defines the string with mixed casing.
string myString = row[0] as String;

// Creates a TextInfo based on the "en-US" culture.
TextInfo myTI = new CultureInfo("en-US", false).TextInfo;

// Retrieve a titlecase'd version of the string.
string myCity = myTI.ToTitleCase(myString);

全部在一行中:

string myCity = new CultureInfo("en-US", false).TextInfo.ToTitleCase(row[0] as String);
