Looking to substitute Enum value for a variable in C#

Question

I have an existing method which essentially hardcodes an Enum value into it.

What I want to do, however, is to pass an Enum value to the method. Then, substitute the passed in value for the hardcoded field. The value that I want to substitute is: ImpactType.Item3ModerateLimited (at the end of the code).

Way method is right now:

strRemedyTktResponse = IssueRemedyTicket(sb1.ToString()); private string IssueRemedyTicket(string webServiceErrInfo) { string strResponse = string.Empty; IncidentService.HPD_IncidentInterface_Create_WSService webService = new IncidentService.HPD_IncidentInterface_Create_WSService(); try { webService.AuthenticationInfoValue = new IncidentService.AuthenticationInfo(); webService.AuthenticationInfoValue.userName = "smocustomer"; webService.AuthenticationInfoValue.password = "ryder123"; webService.Timeout = 1000 * 60; strResponse = webService.HelpDesk_Submit_Service( new[] { ConfigurationManager.AppSettings["AssignedGroup"].ToString() } //Assigned_Group , "" //Assigned_Group_Shift_Name , "Ryder System, Inc." //Assigned_Support_Company , "FMS" //Assigned_Support_Organization , "" //Assignee , "Software" //Categorization_Tier_1 , "Handheld Computer" //Categorization_Tier_2 , "Webservice Failure" //Categorization_Tier_3 , "" //CI_Name , "" //Closure_Manufacturer , "" //Closure_Product_Category_Tier1 , "" //Closure_Product_Category_Tier1 , "" //Closure_Product_Category_Tier3 , "" //Product_Model_Version , "" //Closure_Product_Name , "" //Department , "SMO" //First_Name , ImpactType.Item3ModerateLimited

Definition of ImpactType field:

[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "4.0.30319.18408")] [System.SerializableAttribute()] [System.Xml.Serialization.XmlTypeAttribute(Namespace="urn:HPD_IncidentInterface_Create_WS")] public enum ImpactType { /// <remarks/> [System.Xml.Serialization.XmlEnumAttribute("1-Extensive/Widespread")] Item1ExtensiveWidespread, /// <remarks/> [System.Xml.Serialization.XmlEnumAttribute("2-Significant/Large")] Item2SignificantLarge, /// <remarks/> [System.Xml.Serialization.XmlEnumAttribute("3-Moderate/Limited")] Item3ModerateLimited, /// <remarks/> [System.Xml.Serialization.XmlEnumAttribute("4-Minor/Localized")] Item4MinorLocalized, }

*I was thinking about doing something like below, but am getting the following error on the "Name" property.

Cannot convert from 'string' to 'ImpactType' *

private string IssueRemedyTicket(string webServiceErrInfo, int impactType) { string strResponse = string.Empty; IncidentService.HPD_IncidentInterface_Create_WSService webService = new IncidentService.HPD_IncidentInterface_Create_WSService(); try { webService.AuthenticationInfoValue = new IncidentService.AuthenticationInfo(); webService.AuthenticationInfoValue.userName = "smocustomer"; webService.AuthenticationInfoValue.password = "ryder123"; webService.Timeout = 1000 * 60; var value = ""; if (impactType == 2) value = ImpactType.Item2SignificantLarge.ToString(); else value = ImpactType.Item3ModerateLimited.ToString(); strResponse = webService.HelpDesk_Submit_Service( new[] { ConfigurationManager.AppSettings["AssignedGroup"].ToString() } //Assigned_Group , "" //Assigned_Group_Shift_Name , "Ryder System, Inc." //Assigned_Support_Company , "FMS" //Assigned_Support_Organization , "" //Assignee , "Software" //Categorization_Tier_1 , "Handheld Computer" //Categorization_Tier_2 , "Webservice Failure" //Categorization_Tier_3 , "" //CI_Name , "" //Closure_Manufacturer , "" //Closure_Product_Category_Tier1 , "" //Closure_Product_Category_Tier1 , "" //Closure_Product_Category_Tier3 , "" //Product_Model_Version , "" //Closure_Product_Name , "" //Department , "SMO" //First_Name , ((XmlEnumAttribute)typeof(ImpactType) .GetMember(value.ToString())[0] .GetCustomAttributes(typeof(XmlEnumAttribute), false)[0]).Name

Maybe I'm missing something, but it isn't as simple as treating it like a normal parameter? That is: private string IssueRemedyTicket(string webServiceErrInfo, ImpactType impactType) and passing it into the webService.HelpDesk_Submit_Service call like: , impactType? — Chris Sinclair

If I understand correctly, are you trying to get the XmlEnumAttribute value? If so, you can use reflection as shown here stackoverflow.com/questions/18737950/… — keyboardP

@keyboard, I'm getting the following error when I write use that code: — sagesky36

Also, is 0 the index of the item you want to get. If I want to use the 'SignificantLarge' type, I would use the index of 1? — sagesky36

See https://stackoverflow.com/a/16039343/380384

you want to convert an int into an enum of ImpactType. All you need is this:

ImpactType type = (ImpactType)impactType;

or

, ... , "SMO" //First_Name , (ImpactType)impactType

Thanks so much! That was so much easier :)

btw, the impactType field. Would that be the index of the Enum value? So, if I want the first value from the Impact Enum the impactType would be 0, etc?

Yes, unless you specify a different values to be used.
