Question

c# 文本框显示 MemoryStream 流 然后以字符串形式保存到数据库

Answer 1

textBox.text=memorystream.readtoend().tostring();
查询串= "insert into [tableName] ([指定字段名])values('"+textBox.text+"')";

以上是手敲的，自己输一下吧，不能直接复制的。

using System;
　　using System.IO;
　　using System.Text;
　　class MemStream
　　{
　　static void Main()
　　{
　　int count;
　　byte[] byteArray;
　　char[] charArray;
　　UnicodeEncoding uniEncoding = new UnicodeEncoding();
　　// Create the data to write to the stream.
　　byte[] firstString = uniEncoding.GetBytes(
　　"Invalid file path characters are: ");
　　byte[] secondString = uniEncoding.GetBytes(
　　Path.InvalidPathChars);
　　using(MemoryStream memStream = new MemoryStream(100))
　　{
　　// Write the first string to the stream.
　　memStream.Write(firstString, 0 , firstString.Length);
　　// Write the second string to the stream, byte by byte.
　　count = 0;
　　while(count < secondString.Length)
　　{
　　memStream.WriteByte(secondString[count++]);
　　}
　　// Write the stream properties to the console.
　　Console.WriteLine(
　　"Capacity = {0}, Length = {1}, Position = {2}\n",
　　memStream.Capacity.ToString(),
　　memStream.Length.ToString(),
　　memStream.Position.ToString());
　　// Set the position to the beginning of the stream.
　　memStream.Seek(0, SeekOrigin.Begin);
　　// Read the first 20 bytes from the stream.
　　byteArray = new byte[memStream.Length];
　　count = memStream.Read(byteArray, 0, 20);
　　// Read the remaining bytes, byte by byte.
　　while(count < memStream.Length)
　　{
　　byteArray[count++] =
　　Convert.ToByte(memStream.ReadByte());
　　}
　　// Decode the byte array into a char array
　　// and write it to the console.
　　charArray = new char[uniEncoding.GetCharCount(
　　byteArray, 0, count)];
　　uniEncoding.GetDecoder().GetChars(
　　byteArray, 0, count, charArray, 0);
　　Console.WriteLine(charArray);
　　}
　　}
　　}

是要代码吗？
还是求思路？这个很简单啊
