c#加密，java解密

[tantorplayer]

如题，现在代码已经可以用了，就是有个问题，即用C#加密后，JAVA解密，部分解密过后的数据会显示为乱码，小弟以为是字符集转换的问题，找了半天毛病都没找到，请各位高手帮个忙

c#代码

using System;
using System.Security;
using System.Security.Cryptography;
using System.IO;
using System.Text;
using System.Threading;
namespace WebApplication2
{
/// <summary>
/// DES3 的摘要说明。
/// </summary>
public class DES3
{
public DES3()
{
}
//密钥
private const string sKey = "A3F2569DESJEIWBCJOTY45DYQWF68H1Y";
//矢量，矢量可以为空
private const string sIV = "qcDY6X+aPLw=";
//构造一个对称算法
private SymmetricAlgorithm mCSP = new TripleDESCryptoServiceProvider();
#region public string EncryptString(string Value)
/// 加密字符串
/// 输入的字符串
/// 加密后的字符串
public string EncryptString(string Value)
{
ICryptoTransform ct;
MemoryStream ms;
CryptoStream cs;
byte[] byt;
mCSP.Key = Convert.FromBase64String(sKey);
mCSP.IV = Convert.FromBase64String(sIV);
//指定加密的运算模式
mCSP.Mode = System.Security.Cryptography.CipherMode.ECB;
//获取或设置加密算法的填充模式
mCSP.Padding = System.Security.Cryptography.PaddingMode.PKCS7;
ct = mCSP.CreateEncryptor(mCSP.Key, mCSP.IV);
byt = Encoding.UTF8.GetBytes(Value);
ms = new MemoryStream();
cs = new CryptoStream(ms, ct, CryptoStreamMode.Write);
cs.Write(byt, 0, byt.Length);
cs.FlushFinalBlock();
cs.Close();
return Convert.ToBase64String(ms.ToArray());
}
#endregion
}
}
