| WriteAllLinesAsync(String, IEnumerable<String>, Encoding, CancellationToken) |
以异步形式创建一个新文件,使用指定编码在其中写入指定的行,然后关闭该文件。Asynchronously creates a new file, write the specified lines to the file by using the specified encoding, and then closes the file. |
WriteAllLinesAsync(String, IEnumerable<String>, CancellationToken)
以异步形式创建一个新文件,在其中写入指定的行,然后关闭该文件。Asynchronously creates a new file, writes the specified lines to the file, and then closes the file.
public static System.Threading.Tasks.Task WriteAllLinesAsync (string path, System.Collections.Generic.IEnumerable<string> contents, System.Threading.CancellationToken cancellationToken = default);
static member WriteAllLinesAsync : string * seq<string> * System.Threading.CancellationToken -> System.Threading.Tasks.Task
Public Shared Function WriteAllLinesAsync (path As String, contents As IEnumerable(Of String), Optional cancellationToken As CancellationToken = Nothing) As Task
参数
- path
- String
要写入的文件。The file to write to.
- contents
- IEnumerable<String>
