ASP.NET Web服务序列化2D阵列

Question

嗨我需要从ASP.NET Web服务返回二维数组。

首先我想这个解决方案：

[WebMethod] 
    public string[,] ReturnMultiDimArray() 
    { 
     var x = new string[,] { { "ab" }, { "cd" } }; 
     return x; 
    } 

我得到错误：

无法序列化System.String类型的对象[，]。多维数组不受支持。

这是好的，所以我试过这种方式。

[WebMethod] 
    public string[][] ReturnMultiDimArray() 
    { 
     string[] y = { "ab", "cd" }; 
     string[] z = { "ef", "gh" }; 
     string[][] x = { y, z }; 
     return x; 
    } 

我得到这个错误：

System.InvalidOperationException: There was an error generating the XML document. ---> System.InvalidCastException: Unable to cast object of type 'System.String[][]' to type 'System.Collections.Generic.List`1[System.Collections.Generic.List`1[System.String]]'.

    at System.Xml.Serialization.XmlSerializer.Serialize(TextWriter textWriter, Object o)

    at System.Web.Services.Protocols.HttpServerProtocol.WriteReturns(Object[] returnValues, Stream outputStream) 
    at System.Web.Services.Protocols.WebServiceHandler.WriteReturns(Object[] returnValues) 
    at System.Web.Services.Protocols.WebServiceHandler.Invoke() 

我如何序列化 “二维数组”？我需要从web方法“2D数组”返回。

使用包装类string[]和返回它的

[Serializable] 
public class StringArray 
{ 
    public StringArray() 
    { 
    } 
    public StringArray(params string[] arr) 
    { 
     this.Array = arr; 
    } 
    public string[] Array; 
} 

MemoryStream m = new MemoryStream(); 
StringArray[] strArr = new StringArray[] { new StringArray("a", "b"), new StringArray("c", "d", "e") }; 
XmlSerializer xs = new XmlSerializer(typeof(StringArray[])); 
xs.Serialize(m,strArr);
