Calling DataSources on Microsoft.Reporting.WinForms.LocalReport fails #38

Closed AlanMichaelDobson closed 3 years ago

Hi

I am getting this error CustomCode(2) : error BC30456: 'RegularExpressions' is not a member of 'System.Text'. in code that ran successfully under .Net Framework but fails under .Net 5 If required I will happily narrow down in a test harness if the data below is not enough

Thank you Alan Dobson

Local property

public Microsoft.Reporting.WinForms.LocalReport Report { get; private set; }

Error Call

this.Report.GetDataSourceNames()

Failure method

public void SetDataSet(DataSet dataset) { this.DataSet = dataset;

foreach (string sDataSourceName in this.Report.GetDataSourceNames()) 
{
    if (dataset.Tables.Contains(sDataSourceName))
    {
        ReportDataSource oDataSource = this.Report.DataSources[sDataSourceName];

        if (oDataSource == null)
        {
            oDataSource = new ReportDataSource(sDataSourceName, dataset.Tables[sDataSourceName]);

            this.Report.DataSources.Add(oDataSource);
        }
        else
        {
            oDataSource.Value = dataset.Tables[sDataSourceName];
        }
    }
}

}

There seems to be an expression in your report that directly or indirectly uses regexes. Please inspect your RDLC for such expression and provide it here so I can replicate the issue locally. Most likely cause is missing assembly reference in VB compiler invocation. In .NET Framework System.Text.RegularExpressions used to live in System.dll, now it is in (unreferenced) System.Text.RegularExpressions.dll.

Hi

Below is the only regex in the XML for the report

Public Function ConvertRtfToTextRegex(ByVal input As String) As String Dim returnValue As String = String.Empty returnValue = System.Text.RegularExpressions.Regex.Replace(input, "{*?\[^{}]+}|[{}]|\\n?[A-Za-z]+\n?(?:-?\d+)?[ ]?", "") Return returnValue End Function

Strange that it references System.Text.RegularExpressions

I have added System.Text.RegularExpressions.dll assembly reference to Roslyn compiler input. Please check if this solves the issue.
