以前写过一段C#，苦于编译才能用。这样的小工具最好是用脚本语言来编写，易于执行，也易于修改。
js 代码 convert.js
--------------------------------------------------
String.prototype.trim=function(){
return this.replace(/(^\s*)|(\s*$)/g, "");
}
String.prototype.ltrim=function(){
return this.replace(/(^\s*)/g,"");
}
String.prototype.rtrim=function(){
return this.replace(/(\s*$)/g,"");
}
String.prototype.startWith=function(str){
var reg = new RegExp("^" + str);
return reg.test(this);
}
var ConvertCode = {
content: "",
run: function(){
console.writeline(this.content);
if( !this.content) return;
var lines = this.content.split(‘\n‘);
var ret = "";
for(var i=0; i<lines.length; i++)
{
var dataInfo = this.convertLine(lines[i]);
if(!dataInfo) continue;
ret = ret + "///<summary>\n";
ret = ret + "///\n";
ret = ret + "///<summary>\n";
ret = ret + ‘[DBColumn("‘ + dataInfo.column + ‘")]\n‘;
ret = ret + "public " + dataInfo.dataType + " " + dataInfo.name + "{get;set;}\n\n";
}
return ret;
},
convertLine: function(line){
line = line.trim();
if(line.length == 0) return null;
var tokens = line.split(/\s+/);
if(tokens.length <= 1) return null;
return {
column: tokens[0],
name: this.toNormalName(tokens[0]),
dataType: this.toDataType(tokens[1])
};
},
toNormalName: function(raw) {
var tokens = raw.split(‘_‘);
var ret = "";
for(var i=0; i<tokens.length; i++)
{
ret = ret + tokens[i].substr(0,1).toUpperCase() + tokens[i].substr(1);
}
return ret;
},
toDataType: function(d) {
if(!d) return null;
if(d.startWith("varchar") || d.startWith("char")) return "string";
if(d.startWith("int")) return "int";
if(d.startWith("number")) return "decimal";
if(d.startWith("date")) return "DateTime";
return null;
}
}
html 代码用于调用它
----------------------------------
<html>
<head>
<meta charset=‘gbk‘ />
<script type=‘text/javascript‘ src="convert.js"></script>
<script language="javascript" type=‘text/javascript‘>
var doparse = function(){
var parser = ConvertCode;
parser.content = document.getElementById(‘content‘).value;
var result = parser.run(content);
document.getElementById(‘divResult‘).value = result;
console.writeline( document.getElementById(‘divResult‘).value);
}
</script>
</head>
<body>
<div><input type="button" value="转换" onclick="javascript:doparse();" style="width:50px; height: 30px;"/></div>
<div style="float:left; width: 500px;">
<textarea id=‘content‘ style="width:500px; height:600px;"></textarea>
</div>
<div style="float:left; width:500px; margin-left:30px;" >
<textarea id="divResult" style="width:500px; height:600px;"></textarea>
</div>
</body>
</html>
