Type Conversion error when making a WCF service request-CodePudding

I am working on a project that makes request to what I think is a WCF service. When I am trying to make the requests and run the program I get this error stack trace:

Can anyone help me understand what this error means exactly?

CodePudding user response：

By the error you are trying to convert an array[] type to a type. Try checking the source value you are getting.

CodePudding user response：

This problem occurs when the svcutil.exe or the Web Services Description Language Tool (Wsdl.exe) are used to generate the client information. When you publish a schema that contains nested nodes that have the maxOccurs attribute set to the "unbounded" value, these tools create multidimensional arrays in the generated datatypes.cs file. Therefore, the generated Reference.cs file contains incorrect types for the nested nodes.

The fix is to basically change the multi-dimensional array in the Reference.cs file related to your service reference to a single dimension.
