在C#中调用Java程序并处理数据解压缩,你可以使用以下步骤:
首先,确保你的Java程序已经实现了数据压缩和解压缩的功能。这里我们使用Java的Deflater
和Inflater
类来实现压缩和解压缩。
在C#中,你可以使用Process
类来启动Java程序并传递参数。为了处理解压缩后的数据,你需要在Java程序中将解压缩后的数据写入到一个文件中,然后在C#程序中读取这个文件。
下面是一个简单的示例:
Java程序(Compressor.java):
import java.io.*;
public class Compressor {
public static void main(String[] args) {
try {
// 压缩数据
byte[] inputData = "Hello, World!".getBytes();
Deflater deflater = new Deflater();
deflater.setInput(inputData);
deflater.finish();
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
byte[] buffer = new byte[1024];
while (!deflater.finished()) {
int compressedDataLength = deflater.deflate(buffer);
outputStream.write(buffer, 0, compressedDataLength);
}
deflater.end();
// 将压缩后的数据写入文件
File outputFile = new File("compressed_data.bin");
FileOutputStream fileOutputStream = new FileOutputStream(outputFile);
fileOutputStream.write(outputStream.toByteArray());
fileOutputStream.close();
System.out.println("Data compressed and saved to " + outputFile.getAbsolutePath());
} catch (IOException e) {
e.printStackTrace();
}
}
}
C#程序(Program.cs):
using System;
using System.Diagnostics;
using System.IO;
class Program
{
static void Main()
{
// 启动Java程序并传递参数
ProcessStartInfo startInfo = new ProcessStartInfo
{
FileName = "java",
Arguments = "-cp . Compressor",
RedirectStandardOutput = true,
UseShellExecute = false,
CreateNoWindow = true
};
using (Process process = new Process { StartInfo = startInfo })
{
process.Start();
process.WaitForExit();
}
// 读取解压缩后的数据
string compressedFilePath = "compressed_data.bin";
string decompressedFilePath = "decompressed_data.txt";
using (FileStream compressedFileStream = new FileStream(compressedFilePath, FileMode.Open))
{
using (FileStream decompressedFileStream = new FileStream(decompressedFilePath, FileMode.Create))
{
byte[] buffer = new byte[1024];
int bytesRead;
while ((bytesRead = compressedFileStream.Read(buffer, 0, buffer.Length)) > 0)
{
// 解压缩数据
Inflater inflater = new Inflater();
inflater.SetInput(buffer, 0, bytesRead);
byte[] decompressedData = new byte[1024];
int decompressedDataLength;
while (!inflater.finished())
{
decompressedDataLength = inflater.inflate(decompressedData);
decompressedFileStream.Write(decompressedData, 0, decompressedDataLength);
}
inflater.end();
}
}
}
Console.WriteLine("Data decompressed and saved to " + decompressedFilePath);
}
}
在这个示例中,Java程序将字符串"Hello, World!"压缩并保存到compressed_data.bin
文件中。C#程序启动Java程序,读取压缩后的数据,并使用Inflater
类将其解压缩,然后将解压缩后的数据保存到decompressed_data.txt
文件中。
