如何将图像转换为二进制并在文本框中获取结果 [英] How to convert image to binary and get result in text box

问题描述

我需要将图像转换为二进制并在文本框中获得结果。



i使用以下函数：



图片在路径D中找到：/person.jpg

I need to convert image to binary and get result in text box .

i using the following function :

Image found in path D:/person.jpg

public static byte[] ImageToBinary(string _path)  
{  
FileStream fS = new FileStream(_path, FileMode.Open, FileAccess.Read);  
byte[] b = new byte[fS.Length];  
fS.Read(b, 0, (int)fS.Length);  
fS.Close();  
return b;  
}

如何在textbox1中接收函数ImageToBinary返回的值？



我在c＃windows表格中工作c＃



我尝试了什么：

推荐答案

你拥有所有部分，你需要做的就是遍历字节数组并将每个数字转换为二进制表示。



请记住，通常有一个最大长度您可能需要手动克服的文本框（使其成为多行/增加最大长度等等。

You have all the parts, all you need to do is loop through the byte array and convert each number to binary representation.

Keep in mind there is usually a max length on a text box that you might have to manually overcome (make it multi-line / increase the max length, etc.

public static byte[] ImageToBinary(string _path)  
{  
    FileStream fS = new FileStream(_path, FileMode.Open, FileAccess.Read);  
    byte[] b = new byte[fS.Length];  
    fS.Read(b, 0, (int)fS.Length);  
    fS.Close();  
    return b;  
}

public static void SetText(string _path) {
    byte[] b = ImageToBinary(_path);
    
    StringBuilder binary = new StringBuilder();

    foreach (var bb in b) {
         binary.Append(Convert.ToString(bb, 2));
    }

    textBox1.Text = binary.ToString(); 

}
