Question

c# StreamWriter 应用中，我想每一行中写入两个不同性质的数据，该怎么写呢

StreamWriter sw = new StreamWriter("D:\\TEST\\testWinform_v1.8(1)\\ID and similarity.txt");
for (int i = 0; i < count1; i++)
{
sw.WriteLine(similar.ShapeRecords[i].ProductID);
sw.WriteLine(similar.ShapeRecords[i].Similarity);
}
我不想让ProductID和Similarity这两个数据分成两行，想在一行显示出来，该怎么做

Answer 1

第一行写入ProductID时不写入换行就行了。
StreamWriter sw = new StreamWriter("D:\\TEST\\testWinform_v1.8(1)\\ID and similarity.txt");
for (int i = 0; i < count1; i++)
{
sw.Write(similar.ShapeRecords[i].ProductID);
sw.WriteLine(similar.ShapeRecords[i].Similarity);
}

Answer 2

把第一个WriteLine改成Write
WriteLine的意思就是写完一段话换行

Answer 3

StreamWriter sw = new StreamWriter("D:\\TEST\\testWinform_v1.8(1)\\ID and similarity.txt");
for (int i = 0; i < count1; i++)
{
sw.WriteLine(similar.ShapeRecords[i].ProductID+" "+similar.ShapeRecords[i].Similarity);
// sw.WriteLine(similar.ShapeRecords[i].Similarity);
}
