Question

我有两个名单:我把他们改成像以下两个分水阵:

double[,] data = new double[voltage.Count(), 2];
for (int i = 0; i < voltage.Count(); i++)
{
    data[i, 0] = voltage[i];
    data[i, 1] = current[i];
}

现在,我正试图通过这一阵列敲响,但我对每一行的电压和流体都具有同样的价值:

foreach (double data in ztr.GetCurveDataForTestType()) //this will return my array
{
    richTextBox1.AppendText("Voltage" + data + "    ---------    ");
    richTextBox1.AppendText("Current" + data + "
");
}

Voltage-0.175 --------- Current-0.175
Voltage-9.930625E-06 --------- Current-9.930625E-06
Voltage-0.171875 --------- Current-0.171875
Voltage-9.53375E-06 --------- Current-9.53375E-06
Voltage-0.16875 --------- Current-0.16875

As you see in the first line both voltage and current are same value that is voltage, and on the second raw they are the same again but this time it is the current value. How can I fix this?

Answer 1

我就此建议使用多维阵列。

相反,你可以做这样的一类:

class Measurement
{
    public double Voltage { get; set; }
    public double Current { get; set; }
}

并改变您的返回方法<代码> IE amountable<Measurement>。在NET4.0中,可使用<代码>Zip:

public IEnumerable<Measurement> GetCurveDataForTestType()
{
    return voltage.Zip(current,
        (v, c) => new Measurement { Voltage = v, Current = c});
}

旧版本。 NET:

public IEnumerable<Measurement> GetCurveDataForTestType()
{
    for (int i = 0; i < voltage.Count(); i++)
    {
        yield return new Measurement
        {
            Voltage = voltage[i],
            Current = current[i]
        };
    }
}

之后,你的法典成为:

foreach (Measurement data in ztr.GetCurveDataForTestType())
{
    richTextBox1.AppendText(
        "Voltage: {0} ---------  Current: {1}", data.Voltage, data.Current);
}

Answer 2

你使用与你制造阵列时相同的 lo:

for (int i = 0; i < data.GetLength(0); i++) {
  richTextBox1.AppendText("Voltage" + data[i, 0] + "    ---------    ");
  richTextBox1.AppendText("Current" + data[i, 1] + "
");
}

Answer 3

Update: This question appears to be a duplicate of How to foreach through a 2 dimensional array?. The linked answer has an alternate solution that enables the use of foreach by switching from a two-dimensional array to an array of array.

foreach with a two aspectsal range, will sequentially re each Double Value in the range (by Design).

例如,鉴于以下两维的双重:

var array = new double[,] { { 0, 1, }, { 2, 3 }, { 4, 5 } };

foreach (var d in array)
{
    Console.WriteLine(d);
}
