Unable to generate a temporary class (result=1). error CS0030: Cannot convert type 'Type[]' to 'Type'?

Question

I get this error after I created a class from my xsd file using the xsd.exe tool. So I searched the net and found a solution. Here is the link: http://satov.blogspot.com/200

Answer 1

For me it helps to patch the XML used to generate the code. It happens when:

<Names>
    <Name></Name>
    <Name></Name>
</Names>

then this is optimized by xsd to double array name entry

What I did is:

<Names>
    <Dummy></Dummy>
    <Name></Name>
    <Name></Name>
</Names>

the xsd doesn't optimize it but leaves the single array name

Answer 2

If its in VB.net then you got to search for ()() in your Reference.vb and replace with()

Answer 3

I got this error.In your solution there is reference.cs file in that file you need to search "[][]" and then there will be two results in it..

After you need to remove one "[]" from "[][]" from both places..

It works for me..

Thanks..

Answer 4

You need to change the type of a member variable in the serialized class. For example if its raising an error like:

Unable to generate a temporary class (result=1). error CS0030: Cannot convert type 'Data[]' to 'Data'.

I ran a search on the Data type name in the generated file, and I found this:

[System.Xml.Serialization.XmlArrayItemAttribute("Data", typeof(Data), IsNullable=false)]
public Data[][] Row

Replace Data[][] with Data[] - Change the type of Data from a 2D array to a 1D array. It would solve your problem. :)

Answer 5

Had the same problem, but Xsd2Code didn't integrate with VS2012. So instead I went to my xsd.exe generated .cs file and did:

Find [][] Replace []

which worked.

Answer 6

Add <xs:attribute name="tmp" type="xs:string" /> after every
<xs:sequence maxOccurs="unbounded"> <xs:element ../> </xs:sequence>
and
<xs:sequence> <xs:element maxOccurs="unbounded"/> </xs:sequence>
element in your schema file if you don't want to loose dimension of the array.
