            string pascalName;
            Console.WriteLine("请输入一个字符串,各单词以空格分隔:");
            name = Console.ReadLine();
            pascalName = ConvertToPascal(name);
            Console.WriteLine("按Pascal规则转换后的名称是:"+pascalName);
            Console.ReadLine();
            
        }
        private static string ConvertToPascal(string name)
        {
            string pascalName;
            string tempWord;
            string[] words;

           
            words = name.Split(' ');

            
        
        
            for (int i = 0; i<=words.Length; i++)
            {
                tempWord = words[i].Substring(0, 1).ToUpper();
                pascalName = pascalName + tempWord;
           

                tempWord = words[i].Substring(1).ToLower();
                pascalName = pascalName + tempWord;

            }
            return pascalName;
           }
    }
}

为什么会报pascalName没有赋值，我这个是Pascal字符串转换法，请问改怎么修改？谢谢拉

private static string ConvertToPascal(string name)
        {
            [red]string pascalName="";[/red]
            string tempWord;
            string[] words;

你使用 pascalName = pascalName + tempWord; 时，pascalName的确是没有值的；

加个pascalName ="";

不是没值.是指针指向一个不明确的地址.里面是乱7 8遭的01组合

同楼上！

谢谢各位了!

C# 编译器在编译源文件时将检查出未赋初值的变量（变量初始化），并要求必须初始化变量（即使值类型一般有其类型的默认值，引用类型默认为 null）。
