如何在 C# 中读取 SQLite 数据库中的换行符？

Question

我目前正在开发的应用程序需要检索存储在 SQLite 数据库中的 TEXT 字段中的 Newline (\n) 字符。 SQLite中\n对应的字符是什么？因为

string[] words = str.Split(new string[] { @"\r\n" }, StringSplitOptions.None);

好像不行。

Answer 1

string[] words = str.Split(new string[] { "\r\n" }, StringSplitOptions.None);

在""之前没有@，否则就是\和r和\和n...或者试试

string[] words = str.Split(new string[] { "\n" }, StringSplitOptions.None);

取决于程序在数据库中保存的内容。

现在，如果你真的想抓到任何东西，你可以...

string[] words = str.Split(new[] { "\r\n", "\r", "\n", StringSplitOptions.None);

@means

A verbatim string literal consists of an @ character followed by a double-quote character, zero or more characters, and a closing double-quote character. A simple example is @"hello". In a verbatim string literal, the characters between the delimiters are interpreted verbatim, the only exception being a quote-escape-sequence. In particular, simple escape sequences and hexadecimal and Unicode escape sequences are not processed in verbatim string literals. A verbatim string literal may span multiple lines.

Answer 2

您可以随时使用 Environment.NewLine。

// Summary:
//     Gets the newline string defined for this environment.
//
// Returns:
//     A string containing "\r\n" for non-Unix platforms, or a string containing
//     "\n" for Unix platforms.
   public static string NewLine { get; }


string[] words = str.Split(new[] { Environment.NewLine} , StringSplitOptions.None);
