C# 判断两个文件内容是否一致

file1和file2是两个需要比较的文件

bool IsSameFile( string file1, string file2 )

{

if( file1 == file2 ) {

return true;

}

int file1byte = 0;

int file2byte = 0;

using( FileStream fs1 = new FileStream( file1, FileMode.Open ),

fs2 = new FileStream( file2, FileMode.Open ) ) {

if( fs1.Length != fs2.Length ) {

fs1.Close();

fs2.Close();

return false;

}

do {

file1byte = fs1.ReadByte();

file2byte = fs2.ReadByte();

}

while( ( file1byte == file2byte ) && ( file1byte != -1 ) );

fs1.Close();

fs2.Close();

}

return ( ( file1byte - file2byte ) == 0 );

}
