更改后的数据恢复中的价值

Question

我正在通过数据表进行迭代并进行一些比较。如果值匹配我将标志设置为true。 我有几个情况下它找到了匹配项，设置了标志（设置后立即对其进行验证），在下一个代码中，标志又回到了false。

这是正在检查事物的代码：

foreach (string code in codeList)
{
    // Filters DataTable by code (should be 6 per code)
    expression = $"[Reason Code] = '{code}'";
    _foundRows = ReasonCodeTable.Select(expression);

    // Goes through the filtered rows
    for (int i = 0; i < _foundRows.Length; i++)
    {
        // Index of Source Row
        int _idx = Convert.ToInt32(_foundRows[i][0]);

        // Desc of Source Row
        string _strDesc = _foundRows[i][5].ToString();

        for (int x = 0; x < _foundRows.Length; x++)
        {
            // Index of the 2nd pass
            int _idx2 = Convert.ToInt32(_foundRows[x][0]);

            // Desc of the 2nd pass row
            string _strDesc2 = _foundRows[x]["Description"].ToString();

            Console.WriteLine($"{code}:  Comparing idx1 {_idx}: '{_strDesc}'  vs  idx2 {_idx2}: '{_strDesc2}'");

            // Loops through filtered list again to compare Descriptions and mark as Found
            if (_idx2 != _idx)
            {
                // Compares Descriptions
                if (_strDesc2.ToString() == _strDesc.ToString())
                {
                    Console.WriteLine($"MATCH FOUND (idx1: {_idx} = idx2: {_idx2})");

                    Console.WriteLine($"idx1 {_idx} Before: {ReasonCodeTable.Rows[_idx]["Found"]}");
                    ReasonCodeTable.Rows[_idx]["Found"] = "True";
                    Console.WriteLine($"idx1 {_idx} After: {ReasonCodeTable.Rows[_idx]["Found"]}");

                    Console.WriteLine($"idx2 {_idx2} After: {ReasonCodeTable.Rows[_idx2]["Found"]}");
                    ReasonCodeTable.Rows[_idx2]["Found"] = "True";
                    Console.WriteLine($"idx2 {_idx2} After: {ReasonCodeTable.Rows[_idx2]["Found"]}");

                    Console.WriteLine($"");
                    x = _foundRows.Length;
                }
            }
        }
    }
}

为我提供以下输出。您可以看到它将所有标志设置为真。

4:  Comparing idx1 51: 'Warehouse use and expense'  vs  idx2 51: 'Warehouse use and expense'
4:  Comparing idx1 51: 'Warehouse use and expense'  vs  idx2 52: 'Warehouse use and expense'
MATCH FOUND (idx1: 51 = idx2: 52)
idx1 51 Before: False
idx1 51 After: True
idx2 52 After: False
idx2 52 After: True

4:  Comparing idx1 52: 'Warehouse use and expense'  vs  idx2 51: 'Warehouse use and expense'

idx2 51 After: True
idx2 51 After: True

4:  Comparing idx1 53: 'Warehouse use and expense'  vs  idx2 51: 'Warehouse use and expense'
MATCH FOUND (idx1: 53 = idx2: 51)
idx1 53 Before: False
idx1 53 After: True
idx2 51 After: True
idx2 51 After: True

7:  Comparing idx1 54: 'Lost Inventory'  vs  idx2 54: 'Lost Inventory'
7:  Comparing idx1 54: 'Lost Inventory'  vs  idx2 55: 'Lost Inventory'
MATCH FOUND (idx1: 54 = idx2: 55)
idx1 54 Before: False

idx2 55 After: False
idx2 55 After: True

7:  Comparing idx1 55: 'Lost Inventory'  vs  idx2 54: 'Lost Inventory'
MATCH FOUND (idx1: 55 = idx2: 54)
idx1 55 Before: True
idx1 55 After: True
idx2 54 After: True
idx2 54 After: True

7:  Comparing idx1 56: 'Lost Inventory'  vs  idx2 54: 'Lost Inventory'
MATCH FOUND (idx1: 56 = idx2: 54)
idx1 56 Before: False
idx1 56 After: True
idx2 54 After: True
idx2 54 After: True

6:  Comparing idx1 57: 'Customer Samples'  vs  idx2 57: 'Customer Samples'
6:  Comparing idx1 57: 'Customer Samples'  vs  idx2 58: 'Customer Samples'
MATCH FOUND (idx1: 57 = idx2: 58)
idx1 57 Before: False
idx1 57 After: True
idx2 58 After: False
idx2 58 After: True

6:  Comparing idx1 58: 'Customer Samples'  vs  idx2 57: 'Customer Samples'
MATCH FOUND (idx1: 58 = idx2: 57)
idx1 58 Before: True
idx1 58 After: True
idx2 57 After: True
idx2 57 After: True

6:  Comparing idx1 59: 'Customer Samples'  vs  idx2 57: 'Customer Samples'
MATCH FOUND (idx1: 59 = idx2: 57)
idx1 59 Before: False
idx1 59 After: True
idx2 57 After: True
idx2 57 After: True

就在下面，我有以下代码：

// Marks remaining items as either 'Missing' or 'Inconsistent Description'
            foreach (DataRow _dr in ReasonCodeTable.Rows)
            {
                if ((_dr["Issue"].ToString() == "") && (_dr["Found"].ToString() == "False"))
                {
                    Console.WriteLine($"idx: {_dr["ID"]}");
                    Console.WriteLine($"Code: {_dr["Reason Code"]}");
                    Console.WriteLine($"Issue: {_dr["Issue"]}");
                    Console.WriteLine($"Found: {_dr["Found"]}");
                    Console.WriteLine($"");
                    _dr["Issue"] = "Inconsistent Description";
                }
                else if ((_dr["Issue"].ToString() == "Missing"))
                    _dr["Found"] = false;
            }

我得到了此输出，该输出显示了上面设置的几个索引true又回到了false（特定于53、56、59），

idx: 27
Code: 20
Issue:
Found: False

idx: 53
Code: 4
Issue:
Found: False

idx: 59
Code: 6
Issue:
Found: False

idx: 56
Code: 7
Issue:
Found: False

idx: 68
Code: GENERAL
Issue:
Found: False

我不明白为什么[ “找到”]列正在恢复。
