为什么 .txt 文件输出中的每一行都以“System.int32"结尾?C# [英] Why does every line in the .txt-file output end with 'System.int32'? C#
问题描述
C#,控制台应用程序,虚拟工作室 2015,并行:Windows 8.1.
C#, Console Application, Virtual Studio 2015, Paralelles: Windows 8.1.
代码如下:
class txt_program
{
public void txt()
{
/* 0 */
int[] M_array_0 = { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };
/* 1 */
int[] M_array_1 = { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };
/* 2 */
int[] M_array_2 = { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };
// etc.
// the M matrix
int[][] M = { M_array_0, M_array_1, M_array_2, M_array_3, M_array_4,
M_array_5, M_array_6, M_array_7, M_array_8, M_array_9, M_array_10,
M_array_12, M_array_13 };
// the time pick is beeing called into this item.
Time_pick_2 T2 = new Time_pick_2();
// the if loop making
// 0
if (T2.M_build_0() == true)
{
int nr_0 = 0;
for (int i = nr_0; i < nr_0 + 2; i++)
{
M[1][i] = M_array_0[i] + 1;
}
}
// 1
else if (T2.M_build_1() == true)
{
int nr_1 = 1;
for (int i = nr_1; i < nr_1 + 2; i++)
{
M[1][i] = M_array_1[i] + 1;
}
}
// 2
else if (T2.M_build_2() == true)
{
int nr_2 = 2;
for (int i = nr_2; i < nr_2 + 2; i++)
{
M[2][i] = M_array_2[i] + 1;
}
}
// etc.
using (StreamWriter SW = new StreamWriter(@"txt.txt"))
{
// the loops creating the .txt-file.
for (int i = 0; i < M.GetLength(0); i++)
{
for (int a = 0; a < 13; a++)
{
SW.Write(" " + M[i][a]);
}
SW.WriteLine(M);
}
}
}
}
}
作为粘贴箱:
输出如下:
0 0 0 0 0 0 0 0 0 0 0 0 0System.Int32[][]
0 1 1 0 0 0 0 0 0 0 0 0 0System.Int32[][]
0 0 0 0 0 0 0 0 0 0 0 0 0System.Int32[][]
// etc.
我查看了一些关于 System.Int32[][]
外观的其他帖子,但在所有情况下,代码除了 System.Int32[]
,这意味着代码无法解释创建输出的 for-loop
.这里显示了正确的输出,但仍然以 System.Int32[][]
结尾.为什么会这样,我做错了什么?
I checked some other post about the appearance off System.Int32[][]
but in all of the cases it was code that didnot generate any output except System.Int32[]
, which meant that the code could not interpret the for-loop
creating the output. Here the correct output is displayed but still with the System.Int32[][]
end. Why is this and what am I doing wrong?
推荐答案
您正在内部循环后输出整个数组.如果你想要一个换行符,你可以使用 Console.WriteLine("")
You are outputting the whole array after your inner loop. If you want a newline you could use Console.WriteLine("")
using (StreamWriter SW = new StreamWriter(@"txt.txt"))
{
// the loops creating the .txt-file.
for (int i = 0; i < M.GetLength(0); i++)
{
for (int a = 0; a < 13; a++)
{
SW.Write(" " + M[i][a]);
}
//SW.WriteLine(M); // <-- this line was generating your output
SW.WriteLine("");
}
}
