如何在C＃中将值从文本文件写入复选框 [英] How do I write values from text file to checkbox in C#

问题描述

我有一个用一些变量编写文本文件的程序，我需要将这些文本文件添加到一个清单中，然后将选定的文本文件发送到ftp服务器。

我将留下创建这些文本文件的代码：

I have a program that writes textfiles with some variables and I need to add those textfiles into a checklist and send the selected ones into an ftp server.
I'll leave here the code for creating those text files:

writer.WriteLine($"{numcont};{numenc};{numfatura};{data:dd/MM/yyyy};{valorStr};{zona};");

foreach (ItemTransactionDetail detail in transaction.Details)
{
    var item = MyApp.DSOCache.ItemProvider.GetItem(
        detail.ItemID, 
        MyApp.SystemSettings.BaseCurrency);

    double taxRate = MyApp.DSOCache
                          .TaxesProvider
                          .GetTaxRateFromTaxableGroupID(
                              detail.TaxableGroupID, 
                              "PRT",
                              "CON");

    string barcode = item.BarCode;

    writer.WriteLine($"{barcode};{taxRate};{precoantesdiscStr};{preconetStr};{quantidade};{bonus}");
}

我的尝试：



要填写清单，我已经测试了这个：



但这只是让我的清单空了

What I have tried:

To fill the checklist I've tested this:

But this just leaves my checklist empty

void Form1_Load(object EventArgs)
{
    LoadFileNames();
}

void LoadFileNames()
{
    string path = @"C:\Users\HP8200\Desktop\Faturas Teste";
    string fileNameOnly = "";

    // here you can change file extension according to your needs.
    foreach (var item in System.IO.Directory.GetFiles(path,"*.txt")) 
    {
        fileNameOnly = System.IO.Path.GetFileNameWithoutExtension(item);
        
        // actually adding files names to checkbox listing
        checkedListBox1.Items.Add(fileNameOnly);
    }
}

推荐答案

< span class =code-string> {numcont}; {numenc}; {numfatura}; {data：dd / MM / yyyy}; {valorStr}; {zona};）;

foreach （ItemTransactionDetail detail in transaction.Details）
{
var item = MyApp.DSOCache.ItemProvider.GetItem（
detail.ItemID，
MyApp.SystemSettings.BaseCurrency）;

double taxRate = MyApp.DSOCache
.TaxesProvider
.GetTaxRateFromTaxableGroupID（
detail.TaxableGroupID，
PRT，
CON）;

string barcode = item.BarCode;

writer.WriteLine（

"{numcont};{numenc};{numfatura};{data:dd/MM/yyyy};{valorStr};{zona};"); foreach (ItemTransactionDetail detail in transaction.Details) { var item = MyApp.DSOCache.ItemProvider.GetItem( detail.ItemID, MyApp.SystemSettings.BaseCurrency); double taxRate = MyApp.DSOCache .TaxesProvider .GetTaxRateFromTaxableGroupID( detail.TaxableGroupID, "PRT", "CON"); string barcode = item.BarCode; writer.WriteLine(

{条形码}; {TAXRATE}; {precoantesdiscStr}; {preconetStr}; {quantidade}; {奖金}）;
}

"{barcode};{taxRate};{precoantesdiscStr};{preconetStr};{quantidade};{bonus}"); }

        // actually adding files names to checkbox listing
        checkedListBox1.Items.Add(fileNameOnly);
    }
}

尝试将此行移动到自己的变量：

Try moving this line to its own variable:

foreach (var item in System.IO.Directory.GetFiles(path,"*.txt"))

to：

to:

var files = System.IO.Directory.GetFiles(path,"*.txt");
foreach (var item in files)
{
    // do processing here
}

然后在它上面设置断点，跳过它，检查是否有文件名返回...我的猜测是没有文件，这就是列表的原因是空的......

Then set a breakpoint on it, step over it, and check that there are filenames returned... My guess is that there are no files and that is why the list is empty...
