在将结果写入csv时，数字/文本的格式未正确设置(while writing result into csv , format of number/text not getting set properly)

我正在将数据写入csv。 这样做的时候我将下面的结果写入csv（文件大小以字节为单位）。 FNumber Name Size 1 Save.png 6.89766E+11

我曾尝试使用字符串，long，double作为大小变量，但它没有保留文本或数字格式。 因此，写入的大小看起来像上面或者有时它在大小的末尾追加000000 ..

我希望整个价值看起来像一个数字。

在写入csv之前，请告诉我如何设置文本/数字设置

提前致谢

I am writing data into csv. While doing so I have written below result into csv (size of file is in bytes). FNumber Name Size 1 Save.png 6.89766E+11

I have tried to use string, long, double for size variable but it is not keeping text or number format for that. So written size is looks like above or sometime it is appending 000000 at end of size..

I want whole value should look like a number.

Please let me know how to set text/number setting before writing into csv

Thanks in advance

最满意答案

以下代码应该有效

static void WriteCsvFile() { FileInfo file = new FileInfo(@"<Path of the file>"); StreamWriter writer = new StreamWriter(@"D:\output.csv", false); writer.WriteLine("{0},{1},{2}", "FNumber", "Name", "Size"); writer.WriteLine("{0},{1},{2:D}", "1", "Save.bng", file.Length); writer.Close(); }

The following code should work

static void WriteCsvFile() { FileInfo file = new FileInfo(@"<Path of the file>"); StreamWriter writer = new StreamWriter(@"D:\output.csv", false); writer.WriteLine("{0},{1},{2}", "FNumber", "Name", "Size"); writer.WriteLine("{0},{1},{2:D}", "1", "Save.bng", file.Length); writer.Close(); }
