加載后無法將txt文件保存在c#中

Question

我會盡量使這個簡短。 我正在根據自己的意願制作一個程序，作為視頻游戲（Dark Souls II）的實用程序。該程序的部分功能是將角色構建保存到文本文件中，它還可以加載文本文件並用新信息覆蓋它們。 它需要將 txt 文件拆分成一個可以在加載文件時修改的數組——這樣它就可以將它保存到另一個文件中。 有很多代碼，所以我只會發布相關的內容，但它讓我在特定位置超出范圍，因為它保存文本文件的方式是一條長行，我只能用逗號分隔。

private void btnChar_Click(object sender, EventArgs e)
  {
            string fullChar = full[0] 
                + full[1]
                + full[2]
                + full[3]
                + full[4]
                + full[5]
                + full[6]
                + full[7]
                + full[8]
                + full[9]
                + full[10]
                + full[11]
                + full[12]
                + full[13]
                + full[14]
                + full[15]
                + full[16]
                +full[17];
            FlexibleMessageBox.Show(fullChar);
        }
 private void saveCharacterToolStripMenuItem_Click(object sender, EventArgs e)
        {
            SaveFileDialog saveFileDialog1 = new SaveFileDialog();
            saveFileDialog1.Filter = "Text Documents (.txt)|*.txt";
            saveFileDialog1.DefaultExt = ".text";
            saveFileDialog1.FilterIndex = 2;
            saveFileDialog1.RestoreDirectory = true;
            string fullChar = full[0] + ", "
                + full[1] + ", "
                + full[2] + ", "
                + full[3] + ", "
                + full[4] + ", "
                + full[5] + ", "
                + full[6] + ", "
                + full[7] + ", "
                + full[8] + ", "
                + full[9] + ", "
                + full[10] + ", "
                + full[11] + ", "
                + full[12] + ", "
                + full[13] + ", "
                + full[14] + ", "
                + full[15] + ", "
                + full[16] + ", "
                + full[17] + ", ";
            //Save file dialog for saving characters
            try
            {
                if (saveFileDialog1.ShowDialog() == DialogResult.OK)
                {           
                    //Code to write the stream goes here.
                    File.WriteAllText(saveFileDialog1.FileName, fullChar);               
                }
            }
           catch (Exception etc)
            {
                MessageBox.Show("An error occured: " + etc.Message);
            }
        }

        private void loadCharacterToolStripMenuItem_Click(object sender, EventArgs e)
        {
            OpenFileDialog openFileDialog1 = new OpenFileDialog();
            openFileDialog1.Filter = "Text Documents (.txt)|*.txt";
            openFileDialog1.FilterIndex = 2;
            openFileDialog1.RestoreDirectory = true;
            string fullChar;
            if (openFileDialog1.ShowDialog() == DialogResult.OK)
            {
                //Code to write the stream goes here.
                fullChar = openFileDialog1.FileName;
                full = fullChar.Split(',');
            }
        }         

Answer 1

如果您不確定完整數組的有效長度（您說 18 個元素或更少），那么您不能盲目地假設您擁有所有 18 個元素。

相反，您可以使用string.Join方法來構建要顯示或寫入文件的字符串

private void btnChar_Click(object sender, EventArgs e)
{
    string fullChar = string.Join(",", full);
    FlexibleMessageBox.Show(fullChar);
}

private void saveCharacterToolStripMenuItem_Click(object sender, EventArgs e)
{
    SaveFileDialog saveFileDialog1 = new SaveFileDialog();
    saveFileDialog1.Filter = "Text Documents (.txt)|*.txt";
    saveFileDialog1.DefaultExt = ".text";
    saveFileDialog1.FilterIndex = 2;
    saveFileDialog1.RestoreDirectory = true;
    string fullChar = string.Join(", ", full);        
    //Save file dialog for saving characters
    ......
}

但錯誤的真正原因在於應該取回文件內容的代碼。 在那里，獲得文件名后，您需要閱讀它。
實際代碼只是嘗試拆分文件名。

if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
    fullChar = File.ReadAllText(openFileDialog1.FileName);
    full = fullChar.Split(',');
}
