我有一个文本文件,在其中,它看起来像:
xxxx:value
我想读的只是价值, 我试图操纵:
using System;
using System.IO;
class Test
{
public static void Main()
{
try
{
using (StreamReader sr = new StreamReader("TestFile.txt"))
{
String line = sr.ReadToEnd();
Console.WriteLine(line);
}
}
catch (Exception e)
{
Console.WriteLine("The file could not be read:");
Console.WriteLine(e.Message);
}
}
}
但是我没有太多运气,任何帮助都会很棒。

你需要遍历每一行并拆分每一行......可能应该检查每一行是否为空并且它确实包含一个冒号......但根据你的数据,这可能是不必要的。
using System;
using System.IO;
class Test
{
public static void Main()
{
try
{
using (StreamReader sr = new StreamReader("TestFile.txt"))
{
while (!sr.EndOfStream)
{
String line = sr.ReadLine();
if (line != null && line.Contains(":"))
Console.WriteLine(line.Split(':')[1]);
}
}
}
catch (Exception e)
{
Console.WriteLine("The file could not be read:");
Console.WriteLine(e.Message);
}
}
}

尝试使用string.Split()
:
Console.WriteLine(line.Split(':')[1]);
