拡張子を指定してバックアップ対象から外す C#で増分バックアップができるアプリケーション（6）

ソースコードはこちら
https://github.com/mi3w2a1/incremental-backup

これまではすべてのファイルをバックアップしていましたが、今回は拡張子を指定してそのファイルはバックアップ対象から外す設定ができるようにします。またリストアイテムの項目にメモ欄をつけてなにをバックアップしているのかをわかりやすくしました。

まず設定できる項目が増えたのでBackupFolderInfoクラスのメンバーを増やします（string[] Extensions と string Memo）。

public class BackupFolderInfo
{
    public BackupFolderInfo()
    {
    }

    public BackupFolderInfo(string sourceFolderPath, string targetFolderPath, string[] extensions, string memo)
    {
        SourceFolderPath = sourceFolderPath;
        TargetFolderPath = targetFolderPath;
        Extensions = extensions;
        Memo = memo;
    }
    public string SourceFolderPath = "";
    public string TargetFolderPath = "";
    public string[] Extensions = null;
    public string Memo = "";
}

public class BackupFolderInfo

{

public BackupFolderInfo()

{

}

public BackupFolderInfo(string sourceFolderPath, string targetFolderPath, string[] extensions, string memo)

{

SourceFolderPath = sourceFolderPath;

TargetFolderPath = targetFolderPath;

Extensions = extensions;

Memo = memo;

}

public string SourceFolderPath = "";

public string TargetFolderPath = "";

public string[] Extensions = null;

public string Memo = "";

}

実際にバックアップ対象から外す設定ができるようにします。

public partial class FormFolder : Form
{
    // 追加
    public string Memo = "";
    public string[] Extensions = null;

    protected override void OnLoad(EventArgs e)
    {
        SourceFolderPathTextBox.Text = SourceFolderPath;
        TargetFolderPathTextBox.Text = TargetFolderPath;

        // 追加
        if(Extensions != null)
            ExtensionsTextBox.Text = String.Join(", ", Extensions);
        MemoTextBox.Text = Memo;
        base.OnLoad(e);
    }

    private void buttonOK_Click(object sender, EventArgs e)
    {
        SourceFolderPath = SourceFolderPathTextBox.Text;
        TargetFolderPath = TargetFolderPathTextBox.Text;

        // 追加
        string str = ExtensionsTextBox.Text;
        str = str.Replace(" ", "");
        str = str.Replace("　", "");
        Extensions = str.Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries);
        Memo = MemoTextBox.Text;
    }
}

public partial class FormFolder : Form

{

// 追加

public string Memo = "";

public string[] Extensions = null;

protected override void OnLoad(EventArgs e)

{

SourceFolderPathTextBox.Text = SourceFolderPath;

TargetFolderPathTextBox.Text = TargetFolderPath;

// 追加

if(Extensions != null)

ExtensionsTextBox.Text = String.Join(", ", Extensions);

MemoTextBox.Text = Memo;

base.OnLoad(e);

}

private void buttonOK_Click(object sender, EventArgs e)

{

SourceFolderPath = SourceFolderPathTextBox.Text;

TargetFolderPath = TargetFolderPathTextBox.Text;

// 追加

string str = ExtensionsTextBox.Text;

str = str.Replace(" ", "");

str = str.Replace("　", "");

Extensions = str.Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries);

Memo = MemoTextBox.Text;

}

バックアップの設定を変更したらリストビューコントロールと設定ファイルに反映されるようにしています。

実際にバックアップをするときに特定の拡張子をもつファイルはバックアップの調査対象から外します。またアクセス拒否をされた場合はスキップして処理を続けることができるようにしています。

GetSelectedItemIndex()はリストビューコントロールで上から何番目のアイテムが選択されているかを取得します（一番上は0番目）。

public partial class Form1 : Form
{
    int GetSelectedItemIndex()
    {
        int ret = -1;
        Invoke((Action)(() => {
            var indexes = listView1.SelectedIndices;
            if(indexes.Count == 1)
                ret = indexes[0];
        }));
        return ret;
    }
}

{

int ret = -1;

Invoke((Action)(() => {

var indexes = listView1.SelectedIndices;

if(indexes.Count == 1)

ret = indexes[0];

}));

return ret;

}

GetSourceFolderPath()メソッドはバックアップ元のフォルダパスを取得します。

public partial class Form1 : Form
{
    string GetSourceFolderPath()
    {
        int index = GetSelectedItemIndex();
        if(index != -1)
            return BackupFolderInfos[index].SourceFolderPath;

}

string GetSourceFolderPath()

{

int index = GetSelectedItemIndex();

if(index != -1)

return BackupFolderInfos[index].SourceFolderPath;

else

return "";

}

GetTargetFolderPath()メソッドはバックアップ先のフォルダパスを取得します。

public partial class Form1 : Form
{
    string GetTargetFolderPath()
    {
        int index = GetSelectedItemIndex();
        if(index != -1)
            return BackupFolderInfos[index].TargetFolderPath;

else

}

GetExtensions()メソッドはバックアップの対象外にされている拡張子（「.」は含めない）を取得します。

public partial class Form1 : Form

    string[] GetExtensions()
    {
        int index = GetSelectedItemIndex();
        if(index != -1)
            return BackupFolderInfos[index].Extensions;

if(index != -1)

return BackupFolderInfos[index].Extensions;

}

GetSourceFilePaths()メソッドはバックアップ元のフォルダ内にあるファイルパスを取得します。指定された拡張子は対象から外します。

public partial class Form1 : Form
