是否有一个很好的功能来转变

姓

名字？

Answer 1

请参阅：.NET - How can you split a "caps" delimited string into an array?

特别是：

Regex.Replace("ThisIsMyCapsDelimitedString", "(\\B[A-Z])", " $1")

Answer 2

这是我广泛用于此类事情的扩展方法

public static string SplitCamelCase( this string str )
{
    return Regex.Replace( 
        Regex.Replace( 
            str, 
            @"(\P{Ll})(\P{Ll}\p{Ll})", 
            "$1 $2" 
        ), 
        @"(\p{Ll})(\P{Ll})", 
        "$1 $2" 
    );
}

它还处理像“IBMMakeStuffAndSellIt”这样的字符串，将其转换为“IBM Make Stuff And Sell It”（IIRC）

Answer 3

您可以使用正则表达式：

Match    ([^^])([A-Z])
Replace  $1 $2

在代码中：

String output = System.Text.RegularExpressions.Regex.Replace(
                  input,
                  "([^^])([A-Z])",
                  "$1 $2"
                );

Answer 4

最简单的方法：

var res = Regex.Replace("FirstName", "([A-Z])", " $1").Trim();

Answer 5

    /// <summary>
    /// Parse the input string by placing a space between character case changes in the string
    /// </summary>
    /// <param name="strInput">The string to parse</param>
    /// <returns>The altered string</returns>
    public static string ParseByCase(string strInput)
    {
        // The altered string (with spaces between the case changes)
        string strOutput = "";

        // The index of the current character in the input string
        int intCurrentCharPos = 0;

        // The index of the last character in the input string
        int intLastCharPos = strInput.Length - 1;

        // for every character in the input string
        for (intCurrentCharPos = 0; intCurrentCharPos <= intLastCharPos; intCurrentCharPos++)
        {
            // Get the current character from the input string
            char chrCurrentInputChar = strInput[intCurrentCharPos];

            // At first, set previous character to the current character in the input string
            char chrPreviousInputChar = chrCurrentInputChar;

            // If this is not the first character in the input string
            if (intCurrentCharPos > 0)
            {
                // Get the previous character from the input string
                chrPreviousInputChar = strInput[intCurrentCharPos - 1];

            } // end if

            // Put a space before each upper case character if the previous character is lower case
            if (char.IsUpper(chrCurrentInputChar) == true && char.IsLower(chrPreviousInputChar) == true)
            {   
                // Add a space to the output string
                strOutput += " ";

            } // end if

            // Add the character from the input string to the output string
            strOutput += chrCurrentInputChar;

        } // next

        // Return the altered string
        return strOutput;

    } // end method

正则表达式：

（可能是最好的 - 见第二个答案） http://bytes.com/topic/c-sharp/answers/277768-regex-convert-camelcase-into-title-case

要从UpperCamelCase转换为   标题案例，使用此行：   Regex.Replace（ “UpperCamelCase”，@ “（\ B [A-Z]）”，@”   $ 1" ）;

从lowerCamelCase转换   和UpperCamelCase到Title Case，使用   MatchEvaluator：公共字符串   toTitleCase（Match m）{char   C = m.Captures [0]。价值[0];返回   （（c取代; = 'A'）及及（℃下= 'Z'））Char.ToUpper（c）中的ToString（）：”？   “+ c;}并改变你的正则表达式   用这一行：   Regex.Replace（“UpperCamelCase或   lowerCamelCase”，@ “（\ B [A-Z] | \ B [A-Z]）”，新   MatchEvaluator（toTitleCase））;
