本文介绍了error：System.FormatException：'输入字符串的格式不正确的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 你好，我在尝试创建一个表格时会出错，该表格将随机显示2个玩家的3个骰子值，并将比较数字和显示谁赢了。运行得很好但是在我放入IF语句后它开始显示错误。代码运行但是当我点击"Play！"时它会返回错误。按钮。I am getting a error when trying to create a Form that will randomly display 3 values of 3 Dice for 2 players and will compare the numbers and displays who won. The is running great but it started show me an error after I put the IF statement. The code runs but it returns the error when I click on "Play!" button.问题是我在"错误列表"中没有收到任何错误。所以程序正在运行但是当我点击"播放"时它会冻结并弹出错误消息"System.FormatException：'输入字符串格式不正确" 在该行： The problem is that I am not getting any error in the "Error List" so the program is running but when I click on "Play" it freezes and pops up the error message "System.FormatException: 'Input string was not in a correct format" at the line:  int P1R = Convert.ToInt32（Player1_Result.Text）; 。我相信我的问题是在Int和String ...我运行调试器但没有到达任何地方。 int P1R = Convert.ToInt32(Player1_Result.Text); . I believe that my issue is in Int and String... I ran the debugger but not getting anywhere. 你能帮忙吗...谢谢 Dice1_input_Player1.Text = dice_Player1 [0] .ToString（）; Dice2_input_Player1.Text = dice_Player1 [1] .ToString（）; Dice3_input_Player1.Text = dice_Player1 [2] .ToString（）; Dice1_input_Player2.Text = dice_Player2 [0] .ToString（）; Dice2_input_Player2.Text = dice_Player2 [1] .ToString（）; Dice3_input_Player2.Text = dice_Player2 [2] .ToString（）; Player1_Result.Text = string.Format（" Player 1：{0} {1} {2}"，Dice1_input_Player1.Text，Dice2_input_Player1.Text，Dice3_input_Player1.Text）; Player2_Result.Text = string.Format（" Player 2：{0} {1} {2}"，Dice1_input_Player2.Text，Dice2_input_Player2.Text，Dice3_input_Player2.Text）; int P1R = Convert.ToInt32（Player1_Result.Text）; int P2R = Convert.ToInt32（Player2_Result.Text）; if（P1R> = P2R） Console.Write（" Player 1 Wins！"）; else Console.Write（" Player 2 Wins！"）;Dice1_input_Player1.Text = dice_Player1[0].ToString();Dice2_input_Player1.Text = dice_Player1[1].ToString();Dice3_input_Player1.Text = dice_Player1[2].ToString();Dice1_input_Player2.Text = dice_Player2[0].ToString();Dice2_input_Player2.Text = dice_Player2[1].ToString();Dice3_input_Player2.Text = dice_Player2[2].ToString();Player1_Result.Text = string.Format("Player 1: {0}{1}{2}", Dice1_input_Player1.Text, Dice2_input_Player1.Text, Dice3_input_Player1.Text);Player2_Result.Text = string.Format("Player 2: {0}{1}{2}", Dice1_input_Player2.Text, Dice2_input_Player2.Text, Dice3_input_Player2.Text);int P1R = Convert.ToInt32(Player1_Result.Text);int P2R = Convert.ToInt32(Player2_Result.Text);if (P1R >= P2R)Console.Write("Player 1 Wins!");elseConsole.Write("Player 2 Wins!");推荐答案"Convert.ToInt32（Player1_Result.Text）"中的FormatException表示Player1_Result .Text没有包含可以解释为Int32的正确文本。常见的错误是将文本框留空。这不会被解释为零，它会抛出错误。此外，其他任何不是整数（如字母，小数点或空格）将抛出formatException。使用调试器并在该行中放置一个断点并检查您要转换的文本以查看中的内容。A FormatException in "Convert.ToInt32(Player1_Result.Text)" means that Player1_Result.Text did not contain a correct text that could be interpreted as an Int32. A common mistake is to leave the textbox blank. This is NOT interpreted as zero, it throws an error. Also, anything else that is not an integer such as letters, a decimal point or spaces will throw a formatException. Use the debugger and place a breakpoint in that line and examine the text that you are trying to convert to see what's in there. 这篇关于error：System.FormatException：'输入字符串的格式不正确的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
