stream was not readable.
错误原因:
没有指定StreamWriter的写入文件
正确代码示例1:
class="csharpcode">byte[] businessDataByte = dh.downFile(dataActionUrl); logger.InfoFormat("{0}", businessDataByte.Length); StreamWriter sw = new StreamWriter("a.txt")); sw.Write(Encoding.UTF8.GetString(businessDataByte)); sw.Flush(); sw.Close();
示例2:
using System; using System.IO; using System.Text; namespace ConsoleApplication { class Program { static void Main(string[] args) { string fileName = "test.txt"; string textToAdd = "Example text in file"; using (FileStream fs = new FileStream(fileName, FileMode.CreateNew)) { using (StreamWriter writer = new StreamWriter(fs)) { writer.Write(textToAdd); } } } } }
