动软代码生成器之【实体转换器】模版

相信使用动软代码生成器生成三层的人不在少数，三层中一个必不可少的功能就是把DataSet转换为实体，虽然动软提供的有现成的模版，但是仍然觉得不够强大。

于是自己写了一个模版用来生成实体转换器。代码如下：

?

<#@ template language="c#" HostSpecific="True" #>

<#@ output extension= ".cs" #>

<#

    TableHost host = (TableHost)(Host);

    string DbParaHead=host.DbParaHead;

    string DbParaDbType=host.DbParaDbType;

    string preParameter=host.preParameter;

    string ModelSpace = "TJ.Model."+ host.GetModelClass(host.TableName);

    ColumnInfo identityKey=host.IdentityKey;

    string returnValue = "void";

    if (identityKey!=null)

    {        

         returnValue = CodeCommon.DbTypeToCS(identityKey.TypeName);             

    }

#>

public <#= ModelSpace #> ConvertTo<#= host.TableName#>(DataRow row)

{

    <#= ModelSpace #> entity = null;

    if(row != null)

    {

        entity = new <#= ModelSpace #>();

        for (var i = 0; i < row.Table.Columns.Count; i++)

        {

            switch (row.Table.Columns[i].ColumnName.ToLower())

            {

<# foreach (ColumnInfo c in host.Fieldlist) { #>

                case "<#=c.ColumnName.ToLower()#>" : entity.<#= c.ColumnName #> = Convert.<#=GetConvert(c)#>(row[i]);break;

<#}#>

            }

        }

    }

    return entity;

}

<#+

public string GetConvert(ColumnInfo c)

{

    string str = String.Empty;

    switch(CodeCommon.DbTypeToCS(c.TypeName))

    {

        case "int":str="ToInt32";break;

        case "long":str="ToInt64";break;

        case "float":str="ToDecimal";break;

        case "DateTime":str="ToDateTime";break;

        case "string":str="ToString";break;

        case "bool":str="ToBoolean";break;

    }

    return str;

}
