如何将 excel 单元格地址转换为以下表示法："LetterNumber" 到 "Number, Number"，反之亦然？

Answer 1

I'm trying to set the value of Worksheet.Cells[] but it does not except the "B3" kinds of values

Worksheet.Range 是：

Worksheet.Range("A4").Value = "Foo";

如果可以的话，我还建议您不要一次设置一个单元格。在缓慢的互操作调用中每次调用 Cells 或 Range，因此如果将值放在数组中并一次设置整个范围的值，您将获得更好的性能：

int[,] values;
// fill values with integers
Worksheet.Range("A1","D4") = values;

Answer 2

好吧，即使问题不清楚，这里也有一个答案：

How can I convert an excel cells address in the following notation: "LetterNumber" to "Number, Number" and vice-versa?

private const string ALPHABET = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";

public static string ToExcelCoordinates(string coordinates)
{
    string first = coordinates.Substring(0, coordinates.IndexOf(','));
    int i = int.Parse(first);
    string second = coordinates.Substring(first.Length + 1);

    string str = string.Empty;
    while (i > 0)
    {
        str = ALPHABET[(i - 1) % 26] + str;
        i /= 26;
    }

    return str + second;
}

public static string ToNumericCoordinates(string coordinates)
{
    string first = string.Empty;
    string second = string.Empty;

    CharEnumerator ce = coordinates.GetEnumerator();
    while (ce.MoveNext())
        if (char.IsLetter(ce.Current))
            first += ce.Current;
        else
            second += ce.Current;

    int i = 0;
    ce = first.GetEnumerator();
    while (ce.MoveNext())
        i = (26 * i) + ALPHABET.IndexOf(ce.Current) + 1;

    string str = i.ToString();
    return str + "," + second;
}

结果为：

"1,1" -> "A1"
"A1" -> "1,1"
"42,231" -> "AP231"
"AP231" -> "42,231"
