从文件执行C＃代码 [英] Execute C# code from file

问题描述

我必须在按钮点击事件中执行一些c＃代码。

我在记事本中写了一些代码。我能够从记事本中读取所有代码并存储到字符串中。但之后我不知道如何执行这些字符串作为c＃代码



我尝试过：

I have to execute some c# piece of code at button click event.
I have written some piece of code in notepad. I am able to read all code from notepad and storing into string. But after that I don't know how to execute those string as c# code

What I have tried:

string[] lines = System.IO.File.ReadAllLines(@"F:\PragyaNew\Demo.txt");
            foreach (string line in lines)
            {
            CSharpCodeProvider provider = new CSharpCodeProvider();
            CompilerParameters parameters = new CompilerParameters();
            // Reference to System.Drawing library
            parameters.ReferencedAssemblies.Add("System.Drawing.dll");
            // True - memory generation, false - external file generation
            parameters.GenerateInMemory = true;
            // True - exe file generation, false - dll file generation
            parameters.GenerateExecutable = true;
            CompilerResults results = provider.CompileAssemblyFromSource(parameters, line);
            }

path = Server.MapPath（/ folderName / fileName.txt）; //如果你的txt文件在项目本身中

string [] lines;

var list = new List< string>（）;

var fileStream = new FileStream（@ path，FileMode.Open，FileAccess.Read）;

using（var streamReader = new StreamReader（fileStream，Encoding.UTF8））

{

string line;

while（（line = streamReader.ReadLine（）） ！= null）

{

list.Add（line）;

}

}

lines = list.ToArray（）;



StringBuilder builder = new StringBuilder（）;

foreach（行中的字符串值） ）

{

builder.Append（value）;

builder.Append（
）;

}

div_Content.InnerHtml = builder.ToString（）;



可能有助于读取c＃div_Content中的txt文件是我的div id 路径是你的路径位置

path = Server.MapPath("/folderName/fileName.txt");//if your txt file is in project itself
string[] lines;
var list = new List<string>();
var fileStream = new FileStream(@path, FileMode.Open, FileAccess.Read);
using (var streamReader = new StreamReader(fileStream, Encoding.UTF8))
{
string line;
while ((line = streamReader.ReadLine()) != null)
{
list.Add(line);
}
}
lines = list.ToArray();

StringBuilder builder = new StringBuilder();
foreach (string value in lines)
{
builder.Append(value);
builder.Append("
");
}
div_Content.InnerHtml = builder.ToString();

may it will help to read the txt file in c# div_Content is my div id path is your path location

我的记事本代码正在执行。我已经解决了。但是我面临的另一个问题是，当我在文本框中输入一些值并提交表单时，我正在尝试加载文件并执行这些文件。文件正在执行，但我无法通过文件代码获取文本框值。

My notepad code is executing. I have solved. But again one problem I am facing that when I enter some value in textbox and submit form then I am trying to load file and executing those file. File is executing but I am not able to get textbox value thorough file code.
