1、自定义方法

/**//// <summary>
/// 转全角的函数(SBC case)
/// </summary>
/// <param name="input">任意字符串</param>
/// <returns>全角字符串</returns>
///<remarks>
///全角空格为12288,半角空格为32
///其他字符半角(33-126)与全角(65281-65374)的对应关系是:均相差65248
///</remarks>
public string ToSBC(string input)
![](/Images/OutliningIndicators/ExpandedBlockStart.gif)
![](/Images/OutliningIndicators/ContractedBlock.gif)
{
//半角转全角:
char[] c = input.ToCharArray();
for (int i = 0; i < c.Length; i++)
![](/Images/OutliningIndicators/ExpandedSubBlockStart.gif)
{
if (c[i] == 32)
![](/Images/OutliningIndicators/ExpandedSubBlockStart.gif)
{

continue;
}
if (c[i] < 127)
c[i] = (char) (c[i] + 65248);

return new string(c);
}

}2、
使用Microsoft.VisualBasic类库 在C#项目中添加引用Microsoft.VisualBasic.dll, 可以在C#程序中直接使用VB.NET中丰富的函数 1// 命令行编译 : csc /r:Microsoft.VisualBasic.dll Test.cs
using Microsoft.VisualBasic;
![](/Images/OutliningIndicators/None.gif)
class Test
![](/Images/OutliningIndicators/ExpandedBlockStart.gif)
![](/Images/OutliningIndicators/ContractedBlock.gif)
{
static void Main()
![](/Images/OutliningIndicators/ExpandedSubBlockStart.gif)
{
string s = "博客园-阿友 [http://conquer.cnblogs.com]";
System.Console.WriteLine(s);
![](/Images/OutliningIndicators/InBlock.gif)
s = Strings.StrConv(s, VbStrConv.Wide, 0); // 半角转全角
s = Strings.StrConv(s, VbStrConv.TraditionalChinese, 0); // 简体转繁体
System.Console.WriteLine(s);
![](/Images/OutliningIndicators/InBlock.gif)
s = Strings.StrConv(s, VbStrConv.ProperCase, 0); // 首字母大写
s = Strings.StrConv(s, VbStrConv.Narrow, 0); // 全角转半角
s = Strings.StrConv(s, VbStrConv.SimplifiedChinese, 0); // 繁体转简体
System.Console.WriteLine(s);
}
}
