Question

我会尽量简短。我正在制作一个我的节目自己的意志，作为视频游戏的实用工具（Dark Souls II。）的一部分程序的作用是将字符构建保存到文本文件中也可以加载文本文件并用新信息覆盖它们。它需要将txt文件拆分为可以在其中修改的数组加载文件 - 这样可以将文件保存到另一个文件。有很多代码，所以我只会发布相关的东西，但它给了我自保存文本的方式以来，在特定位置超出界限文件很长，我只能用逗号分割。

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(',');
            }
        }

如果你不确定整个阵列的有效长度（你说18个元素或更少），那么你不能盲目地假设你拥有所有18个元素。

相反，您可以使用string.Join方法构建要显示或写入文件的字符串

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
    ......
}

但错误的真正原因在于应该获取文件内容的代码。在获取文件名后，您需要阅读它实际代码只是尝试拆分文件名。

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

加载后无法在c＃中保存txt文件
