vb.net同音字查询 查同音字的字典

如何用vb.net将汉字转换成拼音阿

public string hz2py(string hz) //获得汉字的区位码

{

byte[] sarr = System.Text.Encoding.Default.GetBytes(hz);

int len = sarr.Length;

if (len1)

{

byte[] array = new byte[2];

array = System.Text.Encoding.Default.GetBytes(hz);

int i1 = (short)(array[0] - '\0');

int i2 = (short)(array[1] - '\0');

//unicode解码方式下的汉字码

// array = System.Text.Encoding.Unicode.GetBytes(hz);

// int i1 = (short)(array[0] - '\0');

// int i2 = (short)(array[1] - '\0');

// int t1 = Convert.ToInt32(i1,16);

// int t2 = Convert.ToInt32(i2,16);

int tmp=i1*256+i2;

函数：

create function getfirstpy(@a varchar(200))

returns varchar(100)

as

begin

declare @i int,@j int,@result varchar(100)

set @result=''

set @i=len(@a)

set @j=1

while @j=@i

begin

select @result=@result+word from tabpy where cast(substring(@a,@j,1) as varbinary(2)) between b_begin and b_end

set @j=@j+1

end

return @result

end

Q1: vb.net 按关键字查询ACCESS数据库

str1是数字类型而strrow是文字类型vb.net同音字查询，所以出错。。

把str1转成string就可以vb.net同音字查询了。。。

Q2: 如何在vb,net 窗体中实现查询功能

N=length(R);

scatter(C(:,1),C(:,2));

hold on

plot([C(R(1),1),C(R(N),1)],[C(R(1),2),C(R(N),2)])

hold on

for ii=2:N

plot([C(R(ii-1),1),C(R(ii),1)],[C(R(ii-1),2),C(R(ii),2)])

hold on

end
