.net core獲取文件內容

 

參考微軟提供幫助文檔：ASP.NET Core 中的文件提供程序

 

1-注入IWebHostEnvironment：

private IWebHostEnvironment _hostEnvironment;

 

2-讀取根目錄下文件內容（Templates/Index.html）：

IFileProvider fileProvider = this._hostEnvironment.ContentRootFileProvider;
IFileInfo fileInfo = fileProvider.GetFileInfo("Templates/Index.html");

string fileContent = null;

using (StreamReader readSteam = new StreamReader(fileInfo.CreateReadStream()))
{
    fileContent = await readSteam.ReadToEndAsync();
}
