从流中获取TextReader？

Question

我正在尝试使用System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream(resource);来读取嵌入的文本文件，但它给了我一个Stream。嵌入式资源是一个文本文件，所以我怎样才能把这个Stream变成TextReader？

Answer 1

TextReader tr = new StreamReader(stream); 

Answer 2

一个StreamReader是TextReader一个子类，所以你可以做：

using(var stream = System.Reflection.Assembly.GetExecutingAssembly(). 
    GetManifestResourceStream(resource)) 
using(var reader = new StreamReader(stream)) 
{ 
    // Use reader. 
} 

Answer 3

你可以这样写的资源文件：

Assembly resourceAssembly = Assembly.LoadFrom(resourceFile.FullName); 
string[] manifests = resourceAssembly.GetManifestResourceNames(); 

using (ResourceReader reader = new ResourceReader(
    resourceAssembly.GetManifestResourceStream(manifests[0]))) 
{ 
    foreach (IDictionaryEnumerator dict in reader) 
    { 
     string key = dict.Key as string; 
     object val = dict.Value; 
    } 
} 

Answer 4

你需要得到它的StreamReader（TextReader是StreamReader和StringReader的抽象基类）。例如：

var stream = System.Reflection.Assembly.GetExecutingAssembly(). 
    GetManifestResourceStream(resource); 
var reader = new StreamReader(stream); 
var text = reader.ReadToEnd();
