Question

我正在这样做。

TextWriter tw = new StreamWriter("SQL_U.txt");
for (int j = 0; j < matrix.ColumnCount; j++)
{
     for (int i = 0; i < matrix.RowCount; i++)
     {
      tw.WriteLine(U[i, j] + " ");
     }
}
tw.Close();

How to fix it?

Answer 1

使用Write,而不是><><>/code> <><>><>><>>>>><>>>>><<>>>>><>>>>><>>>>><>>>><>>>>><>>>>>><>>>>>>><<<>>>>>><>>>>>>>>>>>>>>><>>>>>>>>>>><>>>>>>>>>>>>>>>>>>>>>>>>>> 然后在每行完后插入一条新行。

using (TextWriter tw = new StreamWriter("SQL_U.txt"))
{
    for (int j = 0; j < matrix.ColumnCount; j++)
    {
        for (int i = 0; i < matrix.RowCount; i++)
        {
            tw.Write(U[i, j] + " ");
        }
        tw.WriteLine();
    }
}

我也修改了你的代码,以使用<条码>,使用<>条码/代码>,而不是打上<条码>,使作者即使在有例外的情况下也得到正确处理。

Using this method you also write an extra space at the end of each line. If this is a problem you might want to modify your code slightly to write this space conditionally depending on the index.

using (TextWriter tw = new StreamWriter("SQL_U.txt"))
{
    for (int j = 0; j < matrix.ColumnCount; j++)
    {
        for (int i = 0; i < matrix.RowCount; i++)
        {
            if (i != 0)
            {
                tw.Write(" ");
            }
            tw.Write(U[i, j]);
        }
        tw.WriteLine();
    }
}

Answer 2

这是因为你正在使用<条码>。
