我注意到的一件事是,我只在servers.dat为空时收到错误,但如果它已经保存了服务器,则不会收到错误
有人能帮我吗
提前感谢,
编辑:由于steveg89,下面的解决方案解决了问题(更新SaveTo方法):
我注意到他们的NbtFile构造函数试图从文件中读取。它假设文件的格式已经正确。这意味着您必须创建并保存它。他们的API应该为您处理这个问题,但是没有,所以试试这个
if (!File.Exists(RuntimeInfo.getMinecraftDir() + @"\servers.dat"))
{
NbtFile nbt = new NbtFile();
nbt.SaveToFile(RuntimeInfo.getMinecraftDir() + @"\servers.dat", Nbt.Compression.None);
}
我认为更聪明的方法是更正ServerList的SaveTo
方法。这种方法意味着您不必在代码中检查它,但它确实意味着您将使用自己风格的Craft.Net。我想这样做:
public void SaveTo(string file)
{
NbtFile nbt;
if( File.Exists( file ) )
{
nbt = new NbtFile(file);
}
else
{
nbt = new NbtFile();
}
nbt.RootTag = new NbtCompound("");
var list = new NbtList("servers", NbtTagType.Compound);
foreach (var server in Servers)
{
var compound = new NbtCompound();
compound.Add(new NbtString("name", server.Name));
compound.Add(new NbtString("ip", server.Ip));
compound.Add(new NbtByte("hideAddress", (byte)(server.HideAddress ? 1 : 0)));
compound.Add(new NbtByte("acceptTextures", (byte)(server.AcceptTextures ? 1 : 0)));
list.Add(compound);
}
nbt.RootTag.Add(list);
nbt.SaveToFile(file, NbtCompression.None);
}
我用一套完全不同的方法对解决方案进行了大量更新。让我知道其中一个是否有效。我将这两个代码组合在一起:在创建新的NbtFile时,我在第二个代码中设置了第一个代码中的条件说明,这是有效的!最后非常感谢D
if (!File.Exists(RuntimeInfo.getMinecraftDir() + @"\servers.dat"))
{
NbtFile nbt = new NbtFile();
nbt.SaveToFile(RuntimeInfo.getMinecraftDir() + @"\servers.dat", Nbt.Compression.None);
}
public void SaveTo(string file)
{
NbtFile nbt;
if( File.Exists( file ) )
{
nbt = new NbtFile(file);
}
else
{
nbt = new NbtFile();
}
nbt.RootTag = new NbtCompound("");
var list = new NbtList("servers", NbtTagType.Compound);
foreach (var server in Servers)
{
var compound = new NbtCompound();
compound.Add(new NbtString("name", server.Name));
compound.Add(new NbtString("ip", server.Ip));
compound.Add(new NbtByte("hideAddress", (byte)(server.HideAddress ? 1 : 0)));
compound.Add(new NbtByte("acceptTextures", (byte)(server.AcceptTextures ? 1 : 0)));
list.Add(compound);
}
nbt.RootTag.Add(list);
nbt.SaveToFile(file, NbtCompression.None);
}
