无法隐式将类型字符转换为字符串

本文关键字：字符 转换 字符串 类型 | 更新日期: 2023-09-27 18:31:36

我创建了一个播放器类，并从该类为我的菜单驱动的播放器系统创建了一个数组 我正在尝试使用我的GetChar方法来继续显示提示并读取用户在键盘上键入的任何内容Char.TryParse直到可以将输入转换为字符 但是我不断收到错误

无法隐式将类型字符转换为字符串

当我调用我的GetChar方法时。

任何帮助将不胜感激

// Creates a player in the tables if the array is not already full and the name is not a duplicate
static void ProcessCreate(Int32 number, String firstName, String lastName, Int32 goals,
        Int32 assists, Player[] players, ref Int32 playerCount, Int32 MAXPLAYERS)
{
        //Int32 player = 0;
        if (playerCount < MAXPLAYERS)
        {
          number = IOConsole.GetInt32("'nCreate Player: please enter the player's number");
                       //Console.ReadLine();
            if (GetPlayerIndex(number, firstName, lastName, goals, assists, players, ref playerCount) == -1)
            {
                firstName = IOConsole.GetChar("'nCreate Player: please enter the player's First Name");
                  //Console.ReadLine();
                  lastName = IOConsole.GetChar("'nCreate Player: please enter the player's Last  Name");
                 //Console.ReadLine();
                 goals = IOConsole.GetInt32("'nCreate Player: please enter the player's goals");
               Int32.Parse(Console.ReadLine());
               assists = IOConsole.GetInt32("'nCreate Player: please enter the player's assists");
                 //Console.ReadLine();
                InsertPlayer(number, firstName, lastName, goals, assists, players, ref playerCount);
                Console.WriteLine("'n{0,7}   {1,-20}{2, -20}{3,8}{4,8}{5,8}'n", "Number", "First Name", "Last Name", "Goals", " Assists", "Points");
                for (Int32 player = 0; player < playerCount; player++)
                Console.WriteLine("{0,7}   {1,-20}{2, -20}{3,8}{4,8}{5,8}",
              players[player].Number, players[player].FirstName, players[player].LastName,
              players[player].Goals, players[player].Assists, players[player].Points());
                Console.WriteLine();
            }
            else
                Console.WriteLine("'nCreate Player: the player number already exists");
        }
        else
            Console.WriteLine("'nCreate Player: the player roster is already full");
    }

这是我GetChar方法

public static char GetChar(String prompt)
{
        // declare variables
        char validChar;
        while (!Char.TryParse(Console.ReadLine(), out validChar))
        {
            Console.WriteLine("Invalid entery - try again.");
            Console.Write(prompt);
        }
        return validChar;
}

无法隐式将类型字符转换为字符串

while (!Char.TryParse(Console.ReadLine(), out validChar))

在此行中，您正在读取字符串数据，而不是单个字符，因此无法将其分配给"validChar"（方法 Console.ReadLine）。尝试将此方法的调用分配给字符串变量，然后使用索引 [] 运算符获取第一个字符。

或者，您可以使用

public static ConsoleKeyInfo ReadKey()
