如何在Windows窗体应用程序中读取从form1到form2的日志文件的内容 [英] How can I read the contents of log file from form1 to form2 in Windows forms application

问题描述

我正在使用以下命令读取form1中日志文件的内容

Hi,

I am reading the contents of log file in form1 using the following command

private void ReadLogFile(string dataLogFile)
        {
string[] fileContents = null;
fileContents = File.ReadAllLines(Properties.Settings.Default.LogFilePath + dataLogFile);
 }

此功能不返回



现在我需要在form2中使用相同的字符串数组



任何人都可以建议我，我需要使用什么命令？



谢谢

John

This function returns nothing

Now I need to use the same string array in in form2

Can anyone suggest me, what command I need to use for this??

Thanks
John

推荐答案

将其更改为

change it to

 public static  string[] ReadLogFile(string dataLogFile)
        {
string[] fileContents = null;
fileContents = File.ReadAllLines(Properties.Settings.Default.LogFilePath + dataLogFile);
return fileContents ;
 }

现在这将返回数组中的日志文件行..



in Form2 你可以调用这个函数，比如



string [] fileContents = Form2.ReadLogFile（你的文件）;

now this will return the log file lines in an array..

in Form2 you can call this function like

string[] fileContents = Form2.ReadLogFile("your file ");

你有几个选项：

• 使此方法返回字符串数组。
• 声明 fileContents 作为公共成员 Form1 。
• 声明 fileContents 作为的公共静态成员程序 class。
• ...

You have several options:

• Make this method return the string array.
• Declare fileContents as public member of Form1.
• Declare fileContents as public static member of your Program class.
• ...

添加字符串返回键入你的方法，

并返回你正在提取的对象，



最后调用此方法并将其等同于Form2中的数组

As

string Form2Array [] = YourMethodName（）;

Add An String Return Type To Your Method,
And Return The Object That You Are Fetching,

Finally Call This Method And Equate It To Array In Form2
As
string Form2Array[] = YourMethodName();
