未处理的异常：System.FormatException：输入字符串的格式不正确。 at System.Number.StringToNumber（String str，NumberStyles options，NumberBuffer＆amp; number，NumberFormatInfo info，Boolean parseDecimal）在System.Number.ParseInt32（String s，NumberStyles样式，NumberFormatInfo信息）在System.Int32.Parse（String s）

在我将字[k]解析为matrix1 [i，j]的行上，我收到一条错误消息。 Parse在我第一次使用单词[]时工作正常但不是第二次读到的东西。

问题是从内循环内部读取下一行。您需要读取行而不是每个单元格的行。

var numOfMatrix = int.Parse(fileIn.ReadLine().Trim());
var matrices = new int[numOfMatrix][,];
for (var matrixNumber = 0; matrixNumber < numOfMatrix; matrixNumber++)
{
    var nameOfMatrix1 = fileIn.ReadLine().Trim();
    var words = fileIn.ReadLine().Trim().Split(new[] { ' ' }, StringSplitOptions.RemoveEmptyEntries);
    var matrix1H = int.Parse(words[0]);
    var matrix1W = int.Parse(words[1]);

    var matrix1 = matrices[matrixNumber] = new int[matrix1H, matrix1W];            
    // don't use <=
    for (int i = 0; i < matrix1H; i++)
    {
        // read line line outside of the inner loop
        words = fileIn.ReadLine().Trim().Split(new[] { ' ' }, StringSplitOptions.RemoveEmptyEntries);
        // don't use <=
        for (int j = 0; j < matrix1W; j++)
        {
            matrix1[i, j] = int.Parse(words[j]);
        }
    }
}
