Question

我测量wav文件的时间并将其恢复到TimeSpan中。当我查看Timespan时，totalSeconds值是我需要的确切时间！例如：TotalSeconds = 6.6999999999999993 当我把它写入文件时，它将会转到6.7！

我需要文本文件中的确切值！

以下是代码：

TimeSpan duration = GetWavFileDuration(wav);

string[] wavStrings = wav.Split('\\');


using (TextWriter writer = new StreamWriter(wav.Replace(".wav", ".plist"), false, Encoding.UTF8))
{
    writer.NewLine = "\n";
    writer.Write("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" +
             "<!DOCTYPE plist PUBLIC \"-//Apple//DTD PLIST 1.0//EN\" \"http://www.apple.com/DTDs/PropertyList-1.0.dtd\">\n" +
             "<plist version=\"1.0\">\n" +
             "<dict>\n" +
             "\t<key>bundle_id</key>\n" +
             "\t<string>" + folderStrings[folderStrings.Length - 1] + "</string>\n" +
             "\t<key>channels</key>\n" +
             "\t<integer>2</integer>\n" +
             "\t<key>duration</key>\n" +
             "\t<real>" + duration.TotalSeconds.ToString().Replace(',', '.') + "</real>\n" +
             "\t<key>filetitle</key>\n" +
             "\t<string>" + wavStrings[wavStrings.Length - 1] + "</string>\n" +
             "\t<key>sender</key>\n" +
             "\t<string>" + folderStrings[folderStrings.Length - 1] + "</string>\n" +
             "</dict>\n" +
             "</plist>");
}

Answer 1

您可以简单地将TotalSeconds的值写入文件，例如：

TimeSpan ts = new TimeSpan(1234);
File.WriteAllText(@"C:\Temp\TimeTest.txt", ts.TotalSeconds.ToString());
// File contains: 0.0001234

Answer 2

您可以将参数传递给ToString方法：

ts.TotalSecondsToString("0.00"); //2dp Number

ts.TotalSecondsToString("n2"); // 2dp Number

ts.TotalSecondsToString("c2"); // 2dp currency

前两个选项适用于您的问题。

TimeSpan舍入toString（）C＃
