在特定点开始和结束阅读 [英] Start and end reading at a specific point

问题描述

我想从txt文件中读取一个值.我在什么之后开始和结束在特定点.我要读取的值是:

...
fCloudNearFadeDistance = 9000.0000
...

我不知道如何获取"="之后的数字，即."之后的数字，即9000.

到目前为止，我一直在使用此代码从文本文件中获取此类数字，但在读取带有."的数字时会引发异常.

I want to read a value from a txt file. What i''m after starts and ends at specific points. the value i''m trying to read is:

...
fCloudNearFadeDistance=9000.0000
...

I couldn''t figure out how to get the number after "=" and before ".", namely 9000.

Up till now i was using this code to get such numbers from my text file but it throws an exception when reading numbers with "."

Dim cloudfadeout As Integer
For Each k As String In IO.File.ReadLines(dir + "\My Games\Skyrim\SkyrimPrefs.ini")
    If k.Contains("fCloudNearFadeDistance=") Then
        Dim values() As String = k.Split(CChar("="))
        cloudfadeout = Convert.ToInt32(values(1))
    End If
Next
Form2.TrackBar6.Value = cloudfadeout

推荐答案

转换为int之前32请将其转换为十进制，并且不要忘记替换."与，"
像这样

before convert to int 32 pls convert to decimal and dont forget replace "." with ","
like this

cloudfadeout = Convert.ToInt32(Convert.ToDecimal(values(1).Replace(".",",")))
