如何使用StreamReader读取嵌入式资源(文本文件)并将其作为字符串返回?我当前的脚本使用Windows窗体和文本框,允许用户查找和替换未嵌入的文本文件中的文本。
private void button1_Click(object sender, EventArgs e)
{
StringCollection strValuesToSearch = new StringCollection();
strValuesToSearch.Add("Apple");
string stringToReplace;
stringToReplace = textBox1.Text;
StreamReader FileReader = new StreamReader(@"C:\MyFile.txt");
string FileContents;
FileContents = FileReader.ReadToEnd();
FileReader.Close();
foreach (string s in strValuesToSearch)
{
if (FileContents.Contains(s))
FileContents = FileContents.Replace(s, stringToReplace);
}
StreamWriter FileWriter = new StreamWriter(@"MyFile.txt");
FileWriter.Write(FileContents);
FileWriter.Close();
}
我读取了一个嵌入式资源文本文件,使用:
/// <summary>
/// Converts to generic list a byte array
/// </summary>
/// <param name="content">byte array (embedded resource)</param>
/// <returns>generic list of strings</returns>
private List<string> GetLines(byte[] content)
{
string s = Encoding.Default.GetString(content, 0, content.Length - 1);
return new List<string>(s.Split(new[] { Environment.NewLine }, StringSplitOptions.None));
}
示例:
var template = GetLines(Properties.Resources.LasTemplate /* resource name */);
template.ForEach(ln =>
{
Debug.WriteLine(ln);
});
我很恼火,你必须在字符串中始终包含名称空间和文件夹。我想简化对嵌入式资源的访问。这就是我写这个小课堂的原因。欢迎使用和改进!
用法:
using(Stream stream = EmbeddedResources.ExecutingResources.GetStream("filename.txt"))
{
//...
}
类别:
public class EmbeddedResources
{
private static readonly Lazy<EmbeddedResources> _callingResources = new Lazy<EmbeddedResources>(() => new EmbeddedResources(Assembly.GetCallingAssembly()));
private static readonly Lazy<EmbeddedResources> _entryResources = new Lazy<EmbeddedResources>(() => new EmbeddedResources(Assembly.GetEntryAssembly()));
private static readonly Lazy<EmbeddedResources> _executingResources = new Lazy<EmbeddedResources>(() => new EmbeddedResources(Assembly.GetExecutingAssembly()));
private readonly Assembly _assembly;
private readonly string[] _resources;
public EmbeddedResources(Assembly assembly)
{
_assembly = assembly;
_resources = assembly.GetManifestResourceNames();
}
public static EmbeddedResources CallingResources => _callingResources.Value;
public static EmbeddedResources EntryResources => _entryResources.Value;
public static EmbeddedResources ExecutingResources => _executingResources.Value;
public Stream GetStream(string resName) => _assembly.GetManifestResourceStream(_resources.Single(s => s.Contains(resName)));
}
