如何把一串字符串转成字节

Question

就像一个文本一样string name="dklfjskldfjskldfjklsjdf;aklsjd;flkjasdf";
把name转成字节
请问怎么转

Answer 1

使用Encoding.GetTypes方法:
using System.Text;string name="dklfjskldfjskldfjklsjdf;aklsjd;flkjasdf";
byte[] bytes =Encoding.GetBytes(name);

Answer 2

Unicode字符串，每个字符都占两个字节
.length * 2 就是字节数

Answer 3

楼上说的很正确 我帮你整和一下
using System.Text;
string name="dklfjskldfjskldfjklsjdf;aklsjd;flkjasdf";
byte[] bytes =Encoding.Unicode.GetBytes(name);
if(bytes.Length*2>16*1024)
{
Response.Write("<script>alert('大于')</script>");
}
else
{
Response.Write("<script>alert('小于')</script>");
}

Answer 4

去掉 bytes 里 0 的个数

Answer 5

字节长度 = System.Text.Encoding.Default.GetBytes(name).Length;
