C＃使用Dapper和SQL Server标量变量

Question

I am facing a problem which is familiar in declaring a scalar variable. I tried so many tricks and searched in this forum with no use.

Problem

I am using Dapper in my application and after connecting to the SQL Server I'm calling a stored procedure to insert a company into the company table.

The stored procedure works fine in SSMS when executing it manually, but in the application it keeps giving me error you must declare scalar variable in @comp_Addre . All other variables working fine except this one and I really don't understand why.

Code

public void insertComp(string compID, string compName,  string comp_Addressing, string teleComp, string faxComp, string foundDate, string ownername, string license_ID, string taxingID, string licenseExpiring, string cb_country)
{
    using (IDbConnection Connecting = new System.Data.SqlClient.SqlConnection(connectHelper.CnnVal("hrDB")))
    {
        List<companyModel> companies = new List<companyModel>();
        companies.Add(new companyModel { companyID = compID, companyName = compName,  company_Address=comp_Addressing,telephoneNumber = teleComp, faxNumber = faxComp, foundationDate = foundDate, ownerName = ownername, licenseID = license_ID, taxID = taxingID, licenseExpire = licenseExpiring, country=cb_country });
        Connecting.Execute("dbo.InsertComp @CompanyID, @CompanyName,  @comp_Addre, @TelephoneNumber, @FaxNumber, @FoundationDate, @OwnerName, @LicenseID, @TaxID, @LicenseExpire, @Country", companies);
    }
}

I don't have a working Dapper & C# solution on my machine right now, but just by formatting your code a bit better you can see the error/typo in the code.

The code below should work, because I have changed the comp_Addre to company_Address in the parameterized call to the stored procedure.

Of course, you can also keep the comp_Addre in the stored procedure and change the property of companyModel to company_Address .

public void insertComp(string compID, string compName,  string comp_Addressing, string teleComp, string faxComp, string foundDate, string ownername, string license_ID, string taxingID, string licenseExpiring, string cb_country)
{
    using (IDbConnection Connecting = new System.Data.SqlClient.SqlConnection(connectHelper.CnnVal("hrDB")))
    {
        List<companyModel> companies = new List<companyModel>();
        companies.Add(
            new companyModel { 
                companyID = compID, 
                companyName = compName,  
                company_Address = comp_Addressing,
                telephoneNumber = teleComp, 
                faxNumber = faxComp, 
                foundationDate = foundDate, 
                ownerName = ownername, 
                licenseID = license_ID, 
                taxID = taxingID, 
                licenseExpire = licenseExpiring, 
                country = cb_country });

        Connecting.Execute("dbo.InsertComp 
            @CompanyID, 
            @CompanyName,  
            @company_Address, 
            @TelephoneNumber, 
            @FaxNumber, 
            @FoundationDate, 
            @OwnerName, 
            @LicenseID, 
            @TaxID, 
            @LicenseExpire, 
            @Country", companies);
    }
}

Aside from naming the properties the same on both models, I would advice you to check out the naming conventions of the C# language. Reading (and enforcing) them will make your code easier to understand across multiple people/teams and less typo/error prone.
