C# 用C语言在txt文件中写入矩阵#

我用c#做这件事

反而

如何修复它？

使用而不是阻止启动新线路。然后在每行完成后插入新行

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();
    }
}

这是因为您使用的是

WriteLine

，而不是

Write
