Question

你好我有一个叫做StreamWriter的gameWriter。我可以使用字符串构建器来格式化我的Stream Writer吗？我希望结果看起来像这样：playerOneName和playerTwoName是需要编写的变量。有人可以给我看一个示例代码来显示以下内容：

Output:
playerOnename, playerTwoname, _, _, _, _, _, _, _, _, _,


private void WriteData(string playerOneName, string playerTwoName)
    {
        StreamWriter gameStateWriter = null;

        try
        {
            gameStateWriter = new StreamWriter(filepath, true);
            gameStateWriter.WriteLine(playerOneName + " , " + playerTwoName);
        }
        catch (Exception ex)
        {
            txtOutcome.Text = "The following problem ocurred when writing to the file:\n"
               + ex.Message;
        }
        finally
        {
            if (gameStateWriter != null)
                gameStateWriter.Close();
        }
    }

是的，这些是下划线，他们假设代表空间已准备好写入以保存一些文本。

我正在使用Visual Studio '08运行ASP.NET网站和表单。

如何使用字符串生成器的流编写器，虽然我建议使用循环附加到构建器。

StringBuilder builder = new StringBuilder();

builder.Append(playerOneName)
builder.Append(",")
builder.Append(playerTwoName)
builder.Append(",")
StreamWriter  nameWriter = new StreamWriter(filepath, true);
nameWriter.WriteLine(builder.ToString());

您只需将所有变量存储在数组

中

string[] names = {playerOneName, playerTwoName, playerThreName};
foreach(string item in names)
{

    builder.Append(item)
    builder.Append(",")
}

如何在StreamWriter中使用String Builder格式化我的文本文件？
